Add Int8# and Word8#
This is the first step of implementing:
https://github.com/ghc-proposals/ghc-proposals/pull/74
The main highlights/changes:
primops.txt.pp gets two new sections for two new primitive types for
signed and unsigned 8-bit integers (Int8# and Word8 respectively) along
with basic arithmetic and comparison operations. PrimRep/RuntimeRep get
two new constructors for them. All of the primops translate into the
existing MachOPs.
For CmmCalls the codegen will now zero-extend the values at call
site (so that they can be moved to the right register) and then truncate
them back their original width.
x86 native codegen needed some updates, since it wasn't able to deal
with the new widths, but all the changes are quite localized. LLVM
backend seems to just work.
This is the second attempt at merging this, after the first attempt in
D4475 had to be backed out due to regressions on i386.
Bumps binary submodule.
