[clang][PowerPC] Remove remaining Darwin support

[daltenty]

Summary

POWER Darwin support in the backend has been removed for some time: https://discourse.llvm.org/t/rfc-remove-darwin-support-from-power-backends
but Clang still has the TargetInfo and other remnants lying around.

This patch does some cleanup and removes those and other related frontend support still remaining. We adjust any tests using the triple to either remove
the test if unneeded or switch to another Power triple.

This LGTM. Thanks for cleaning it up. Give it at least a week for any others that may have an opinion on this to chime in.
