PSA: GHC can now be built with Clang

[Carter Schonwald]

What branch is that work in? I've not seen mention of it in the commit
logs.  I'd really love to see how they're Doing it.

Likewise, it's worth remarking that a carefullywritten simd primop that
explicitly uses the instruction intrinsics can easily be 1.5-2x faster than
auto vectorized simd code.  I've some examples I tested for matrix
multiplication where the performance is robustly In that range.
