Summary:
Add prettyprinter tests, which take a file, parse it, pretty print it,
re-parse the pretty printed version and then compare the original and
new ASTs (ignoring locations)
Updates haddock submodule to match the AST changes.
There are three issues outstanding
1. Extra parens around a context are not reproduced. This will require an
AST change and will be done in a separate patch.
2. Currently if an `HsTickPragma` is found, this is not pretty-printed,
to prevent noise in the output.
I am not sure what the desired behaviour in this case is, so have left
it as before. Test Ppr047 is marked as expected fail for this.
3. Apart from in a context, the ParsedSource AST keeps all the parens from
the original source. Something is happening in the renamer to remove the
parens around visible type application, causing T12530 to fail, as the
dumped splice decl is after the renamer.
This needs to be fixed by keeping the parens, but I do not know where they
are being removed. I have amended the test to pass, by removing the parens
in the expected output.

This patch reverts the change introduced with
587dcccfdfa7a319e27300a4f3885071060b1f8e and restores the previous
default output of GHC (i.e., show source path and object path for each
compiled module).
The -fhide-source-paths flag can be used to hide these paths and reduce
the line
noise.

* Deprecate -XOverlappingInstances
* Update test suite. Several tests even had entirely unnecessary
uses of -XOverlappingInstances
* Update user manual with a careful description of the instance
resolution story
* Fix an outright bug in the handling of duplidate instances in GHCi,
which are meant to silently overwrite the earlier duplicate. The
logic was right for family instances but was both more complicated,
and plain wrong, for class instances. (If you are interested, the
bug was that we were eliminating the duplicate from the InstEnv, but
not from the [ClsInst] held in tcg_insts.) Test is ghci044a.

This matches GCC's choice of Unicode quotation marks (i.e. U+2018 and U+2019)
and therefore looks more familiar on the console. This addresses #2507.
