Changes

Summary

1. [X86][AVX512] Refine some avx512er intrinsics tests. NFC. The modified tests should test the masked intrinsics. Currently the mask is constant, which with a future patch (https://reviews.llvm.org/D32805) will cause the intrinsics to be replaced with an unmasked version. This patch changes the constant mask to be a variable one.
2. Use a simpler heuristic for placing orphans. This is a bit easier to read and a lot faster in some cases. A version of many-sections.s with linker scripts goes from 0m41.232s to 0m19.575s.
