Subject: [PATCH 1/4] PPC/PPC64: Fix ABI errors.
Issue #1652 seems to be caused by ABI errors in the bootstrap compiler.
This PR updates the PPC/PPC64 ABI to conform to clang/gcc output.

Subject: [PATCH 4/4] Attempt to fix PPC64-LE, MIPS64 and ARM/AArch64 ABIs
Most importantly, make sure sret is enforced for all non-POD structs as
done for all other ABIs, and don't treat extern(D) any different from the
C ABI wrt. return values anymore.
Also reduce code duplication via common TargetABI patterns.
