[PATCH] D134982: [X86] Add support for "light" AVX

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Please do you have any more statistics on what range of machine(s) and test cases you've tried this on (compared to -mattr=prefer-128-bit/256-bit)?

If we think we need this it would definitely be better as a Tuning feature bit (prefer-256-bit-memcpy)?
