cdfb302876 fix an obvious bug found by clang++ and collapse a redundant if. 
Here's the diagnostic from clang:

/Volumes/Data/dgregor/Projects/llvm/lib/Target/CppBackend/CPPBackend.cpp:989:23: warning: 'gv' is always NULL in this context
        printConstant(gv);

252a0dfa6a NNT: Use [e]grep -a when scanning logs, its possibly they will have non-text 
characters in them, in which case the grep will just return 'Binary file
matches' and the whole thing falls over.

for non-intel and non-amd X86 CPUs it is right (VIA, etc.).

c4174d675b Using _MSC_VER there was wrong, better just use the already existing ifdefs for 
x86 CPU detection for the X86 getHostCPUName too, and create a simple
getHostCPUName that returns "generic" for all else.
