I should be sending up some AVX code this week. When I do this
I'd like to generate some testcases to make sure we actually
generate AVX code. Ideally we'd have a testcase for each AVX
pattern but that's probably overkill. Still, we'd like a lot
of tests, I think.
Should these tests go into CodeGen/X86 or should I create a new space,
like CodeGen/X86/SIMD? I tend to favor the latter as it keeps things
more compartmentalized and cleaner.
