    M llvm/unittests/TargetParser/TripleTest.cpp

  Log Message:
  -----------
  [Driver] Properly report error for unsupported powerpc darwin/macos triples

The removal started at https://reviews.llvm.org/D50989 and
https://reviews.llvm.org/D75494 removed the Triple support. Without recognizing
Darwin triples as Mach-O, we will get assertion error in ToolChains/Darwin.h due
to the universal binary mechanism.

Fix #47698

This requires fixing many misuses of llc -march= and llvm-mc -arch= (
