[PATCH] D111485: [Powerpc] store byval parameter to parameter save area when needed

[ChenZheng via Phabricator via llvm-commits]

shchenz added a comment.

I asked for some help from a GCC developer. He told me GCC only copies byval structure bigger than 64 bytes to the parameter save area instead of 8 bytes for ELF64. So now after the change, clang should have the same logic as GCC.
