The trailing TU_MU suffixes was added in D152425 <https://reviews.llvm.org/D152425>. However the original
pattern intend to generate TA_MA policy. Generating TU_MU here is not
incorrect, as TU_MU is one possible resulting behavior for TA_MA, but
this generally slow things down.

Apparently there was also no test coverage to guard such changes.
