Commit 282eff38477ebf665f88f52411edd591067af883 by craig.topper
[X86] Always define the tzcnt intrinsics even when _MSC_VER is defined.
These intrinsics use llvm.cttz intrinsics so are always available even
without the bmi feature. We already don't check for the bmi feature on
the intrinsics themselves. But we were blocking the include of the
header file with _MSC_VER unless BMI was enabled on the command line.
Fixes PR30506.
