Previously the make build system would pass things like
`-optl-optl-Wl,-x -optl-optl-Wl,noexecstack` to GHC. This would
naturally result in mass confusion as GHC would pass `-optl-Wl,-x` to
GCC. GCC would in turn interpret this as `-o ptl-Wl,-x`, setting the
output pass of the invocation.
The problem that `-optl` was added to the command-line in two places in
the build system. Fix this.
Fixes #17385.

The generated headers are now generated per stage, which means we can
skip hacks like `ghc_boot_platform.h` and just have that be the stage 0
header as proper. In general, stages are to be embraced: freely generate
everything in each stage but then just build what you depend on, and
everything is symmetrical and efficient. Trying to avoid stages because
bootstrapping is a mind bender just creates tons of bespoke
mini-mind-benders that add up to something far crazier.
Hadrian was pretty close to this "stage-major" approach already, and so
was fairly easy to fix. Make needed more work, however: it did know
about stages so at least there was a scaffold, but few packages except
for the compiler cared, and the compiler used its own counting system.
That said, make and Hadrian now work more similarly, which is good for
the transition to Hadrian. The merits of embracing stage aside, the
change may be worthy for easing that transition alone.

They are a particular type of perf tests. This patch introduces a
'stats_files_dir' configuration field in the testsuite driver where all
haddock timing files (and possibly others in the future) are assumed to live.
We also change both the Make and Hadrian build systems to pass respectively
$(TOP)/testsuite/tests/perf/haddock/ and
<build root>/stage1/haddock-timing-files/ as the value of that new
configuration field, and to generate the timing files in those directories
in the first place while generating documentation with haddock.
This new test type can be seen as one dedicated to examining stats files that
are generated while building a GHC distribution. This also lets us get rid of
the 'extra_files' directives in the all.T entries for haddock.base,
haddock.Cabal and haddock.compiler.

While windows and macOS are currently on case-insensitive file
systems, this poses no issue on those. When cross compiling from
linux with a case sensitive file system and mingw providing only
lowercase headers, this in fact produces an issue. As such we just
lowercase the import headers, which should still work fine on a
case insensitive file system and also enable mingw's headers to
be usable porperly.

The splitter is an evil Perl script that processes assembler code.
Its job can be done better by the linker's --gc-sections flag. GHC
passes this flag to the linker whenever -split-sections is passed on
the command line.
This is based on @DemiMarie's D2768.

Currently build logs from GitLab CI around around 7 megabytes each. Of this,
around 2 megabytes is latex output. This is quite silly as essentially all of
this output is unresolved references in the early latex iterations.
Here we silence this output.
However, to make sure that we don't silence errors we allow each xelatex
invocation besides the last to fail.

Summary:
This tool can be used to generate dll's for any list of object files
given to it. It will then repartition them automatically to fit within
a dll and generates as many dll's as needed to do this. Cyclic dependencies
between these generated dlls are handle automatically so there is no need
to tell it how to partition.
It is also a lot more general than `dll-split` as it is able to split any
package not just `libGHC`. It also uses a trick using GNU style import libraries
to hide the splitting from the rest of the pipeline. Which means come linking time
you don't need to know which dll contains what symbol or how many split dlls were
created.
The import libraries are by default created with libtool. However since libtool is BFD
based it is very slow. So if present and detected by configure the `genlib` tool
from the msys2 project is used. This makes a difference of about ~45 minutes when compiling.
To install `genlib` run `pacman -Sy mingw-w64-$(uname -m)-tools-git`.

This patch removes dll-split from the code base, the reason is dll-split
no longer makes any sense. It was designed to split a dll in two, but we
now already have many more symbols than would fit inside two dlls. So we
need a third one. This means there's no point in having to maintain this
list as it'll never work anyway and the solution isn't scalable.

Cabal's parser has been rewritten in terms of Parsec (which is not
enabled yet in Cabal-2.0 by default, but can be enabled by a cabal
flag). The plan for Cabal is to drop support for the non-parsec parser,
so we need to prepare GHC to cope with new situation.
However, this means that lib:Cabal requires three new library
dependency submodules,
- parsec
- text
- mtl
What complicates matters is that we need to build `ghc-cabal` early on
during the bootstrap phase which currently needs to invoke `ghc --make`
directly. So these additional dependencies need to be integrated into
the monolithic `ghc --make` invocation which produces the `ghc-cabal`
executable.
Test Plan: `./validate --fast` passed

Summary:
Initial implementation of split-section on Windows.
This also corrects section namings and uses the platform
convention of `$` instead of `.` to separate sections.
Implementation is based on @awson's patches to binutils.
Binutils requires some extra help when compiling the libraries
for GHCi usage. We drop the `-T` and use implicit scripts to amend
the linker scripts instead of replacing it.
Because of these very large GHCi object files, we need big-obj support,
which will be added by another patch.

for a library in stage{0,1,2}.
Usage example:
libraries/binary_EXTRA_HC_OPTS += -O1
libraries/containers_EXTRA_HC_OPTS += -O1
libraries/bytestring_EXTRA_HC_OPTS += -O1
Here override default -O2 defined in .cabal files
for these libraries to speed build up.

Since the introduction of -split-sections, using GHCi with the RTS
linker is really slow:
```
$ time (echo :quit | ./inplace/bin/ghc-stage2 --interactive -fexternal-interpreter)
GHCi, version 8.1.20170304: http://www.haskell.org/ghc/ :? for help
Prelude> Leaving GHCi.
real 0m3.793s
```
(when we use `-fexternal-interpreter` it uses the RTS linker by default,
you can make it use the system linker by adding `-dynamic`)
Building the GHCi libs doesn't take much time or space in the GHC build,
but makes things much quicker for people using the RTS linker:
```
$ time (echo :quit | ./inplace/bin/ghc-stage2 --interactive -fexternal-interpreter)
GHCi, version 8.1.20170304: http://www.haskell.org/ghc/ :? for help
Prelude> Leaving GHCi.

```
So I propose that we build and ship them unconditionally.

After commit a50082c11 we use -ffunction-sections -fdata-sections
for all C compilations, when $1_$2_SplitSections is set. But that
variable was set in build-package.mk which is not run for the RTS.
As a result the RTS was not being split, leading to larger binaries.
This commit fixes RTS splitting by moving the definition of
$1_$2_SplitSections to distdir-opts.mk, which is run for the RTS
(and also from build-package.mk).

This changedoes two things:
- split 'EXTRA_LD_OPTS' into two variables:
- EXTRA_LD_OPTS (accepts 'gcc' wrapper options)
- EXTRA_LD_LINKER_OPTS (accepts raw 'ld' options)
- wraps all LD_LINKER options as '-Wl,' when passed
to 'gcc' driver.

GHC uses gcc, not ld, for linking. Consequently all flags to be
interpreted by ld need to be prefixed by -optl,-Wl on the GHC command
line.

This ensures that artifacts built with build-prog see these options.
Also spruce up comments.
Test Plan: Carefully read it.

Summary:
This omits -L and -l flags from the linker command line that shouldn't
be necessary because GHC will already add them via the -package-id
flags we pass.
This also reverts part of 90538d86af579595987826cd893828d6f379f35a
that rearranges the linker command line and causes some knock-on
problems (see D2618).
Test Plan: validate (need to validate on Windows too)

Previously this was a relative path which worked in the GHC tree, but
failed elsewhere. This caused trouble for out-of-tree users as well as
Hadrian, which wants to move build artifacts out of the working
directory. Fixes #8040.

Previously programs only depended upon the direct dependencies; while I
would have thought that this would be sufficient, somehow we were
getting to the link step of building `ghc-pkg` before `ghc-boot-th` was
built (despite the fact that `ghc-boot` has a direct dependency on
`ghc-boot-th`).
See #12078.

There was a missing `#`. Hadrian couldn't come soon enough.

This may have been the cause of various build failures on FreeBSD and
Solaris.
