r280597 - [AVX-512] Remove masked integer mullo builtins and replace with native IR.

[Craig Topper via cfe-commits]

This failure doesn't make sense. It's acting like the test was updated for
r280596, but not the intrinsic header or the clang binary. That's the only
way I can think that the output IR could contain
@llvm.x86.avx512.mask.padd.b.256.
