[PowerPC][NFC] autogen mma tc checks via update_cc_test_checks (#108584)
Update mma tests in prep for changes needed in a followup patch for
https://github.com/llvm/llvm-project/issues/107229.
Checks for ``clang/test/CodeGen/PowerPC/builtins-ppc-pair-mma-types.c``
seem to have been manually upated to rename temp variables even though
it says checks was auto generated. Regenerate via script.
Add noopt checks for
``clang/test/CodeGen/PowerPC/builtins-ppc-build-pair-mma.c``.
