Pull in r282336 from upstream llvm trunk (by Sanjay Patel):
[x86] don't try to create a vector integer inst for an SSE1 target (PR30512) This bug was introduced with: http://reviews.llvm.org/rL272511 We need to restrict the lowering to v4f32 comparisons because that's all SSE1 can handle. This should fix: https://llvm.org/bugs/show_bug.cgi?id=28044
This avoids a "Do not know how to custom type legalize this operation"
error when building the multimedia/ffmpeg port on i386 with SSE enabled.
