This patch adds powerpc64le Linux support. While the patch also adds the matching powerpc64 bits, there are endian issues that need to be sorted out. The PowerPC LLVM changes for the swift ABI (eg returning three element non-homogeneous aggregates) are still in the works, but a simple LLVM fix to allow those aggregates results in swift passing all but 8 test cases.
