  Changed paths:

    M compiler-rt/test/sanitizer_common/lit.site.cfg.py.in

  Log Message:
  -----------
  [sanitizer-common] Force pickup of llvm-symbolizer from new binaries.

It's possible currently that the sanitizer runtimes when testing grab
the path to the symbolizer through *SAN_SYMBOLIZER_PATH=...

This can be polluted by things like Android's setup script. This patch
forces external_symbolizer_path=$new_build_out_dir/llvm-symbolizer when
%env_tool_options is used.

  Log Message:
  -----------
  [X86] Rename reduction combiners to make it clearer whats happening. NFCI.

Since these are all working on reduction patterns, actually use that term in the function name to make them easier to search for.

At some point we're likely to start working with the ISD::VECREDUCE_* opcodes directly in the x86 backend, but that is still some way off.

    M llvm/test/CodeGen/X86/extract-lowbits.ll

  Log Message:
  -----------
  [X86] Regenerate bit extraction tests, cleaning up check-prefixes.

As noticed on D92965, we needed to simplify the prefixes to ensure all RUNs were properly covered.

We should never have a target with BMI2 without BMI1, so use that as the 'BMI level' and then check with/without TBM (all TBM targets have at least BMI1).
