  -----------
  Reland "[X86][APX] Remove redundant TEST*ri instructions" (#156002)

The goal is to remove redundant TEST*ri instructions, especially with NF
feature. Other tests are side effects due to longer live range of
EFLAGS. https://godbolt.org/z/PbaTj1oa3

Reland with fix to buildbot failures.
