Simd ghc and llvm Re: PSA: GHC can now be built with Clang

[Carter Schonwald]

Which reminds me: should we look into getting a patch into llvm'd ghc
calling convention so that on avx2 capable machines  so we can eventually
add support for the 256bit Ymm resisters and primops to ghc?  We really
should make sure it's patched in on the llvm side first.

I believe it'd be a 2 line patch, might even be something we could get into
the next llvm point release if there's a clear agreement about it too.

Thoughts? I'm happy to put a ticket on trac for this andor do the leg work
to make it happen if everyone agrees.
