[PATCH] D49754: Add -m(no-)spe, and e500 CPU definitions and support to clang

The desired function for this va_arg is not in lib/Target/PowerPC/*.cpp, it is in tools/clang/lib/CodeGen/TargetInfo.cpp , a little bit unexpected to me.
PPC32_SVR4_ABIInfo::EmitVAArg() is doing the va_arg handling. For testing, I have added a hasSPE = true and treat the parameter like SoftFloat. It looks good! Now I need to find out, where to get "hasSPE" from.
