Different x86 microarchitectures support macro-fusion for different
compare and branch combinations. I need to differentiate various x86
microarchitectures. If use TARGET_FUSE_CMP_AND_BRANCH like vars to
control it, it requires a bunch of them. That is why I choose to check
corei7/corei7-avx in that function. I don't add core-avx-i/core-avx2
for now because I don't have those machines for testing.

Thanks,
Wei Mi.
