This patch is for porting existing headers which include x86 intrinsics (MMX, SSE, SSE2, etc.) implementation to PowerPC platform (using Altivec).

Since x86 intrinsic headers (like mmintrin.h) are already at clang's header directory, I overrided PowerPC's toolchain class to insert new headers directory (named ppc_wrappers) into the path. This patch contains tests for several intrinsic functions. More complete tests will come in future patches.

To make this patch not too long, I only added mmintrin.h (MMX instruction set header).
