[PATCH] D36344: [X86] Don't use fsin/fcos/fsincos instructions ever

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

Previously we would use these instructions if sse was disabled and fastmath was enabled.

As mentioned in https://reviews.llvm.org/D28335, this is a bad idea.
