Stefan Pintilie b80357d46e [PowerPC] Add option for ROP Protection
Added -mrop-protection for Power PC to turn on codegen that provides some
protection from ROP attacks.

The option is off by default and can be turned on for Power 8, Power 9 and
Power 10.

This patch is for the option only. The feature will be implemented by a later
patch.

Dimitry Andric fc2dac4116 [PPC] Fix platform definitions when compiling FreeBSD powerpc64 as LE
As a prerequisite to doing experimental buids of pieces of FreeBSD PowerPC64 as little-endian, allow actually targeting it.

This is needed so basic platform definitions are pulled in. Without it, the compiler will only run freestanding.

Lei Huang 2368bf52cd [PowerPC] Add support for -mcpu=pwr10 in both clang and llvm
Summary:
This patch simply adds support for the new CPU in anticipation of
Power10. There isn't really any functionality added so there are no
associated test cases at this time.

Fangrui Song 8edf759ca7 [PowerPC][Triple] Use elfv2 on freebsd>=13 and linux-musl
Summary:
Every powerpc64le platform uses elfv2.

For powerpc64, the environments "elfv1" and "elfv2" were added for
FreeBSD ELFv1->ELFv2 migration in D61950.  FreeBSD developers have
decided to use OS versions to select ABI, and no one is relying on the
environments.

Also use elfv2 on powerpc64-linux-musl.

Users can always use -mabi=elfv1 and -mabi=elfv2 to override the default
ABI.
