[aarch64 NCG] Add better support for sub-word primops
During the intial NCG development, GHC did not have support for
anything below Words. As such the NCG didn't support any of this
either. AArch64-Darwin however needs support for subword, as
arguments in excess of the first eight (8) passed via registers
are passed on the stack, and there in a packed fashion. Thus
ghc learned about subword sizes. This than lead us to gain
subword primops, and these subsequently highlighted deficiencies
in the AArch64 NCG.
This patch rectifies the ones I found through via the test-suite.
I do not claim this to be exhaustive.
