[PATCH] [ARM] Fix ARM triple parsing.

[Renato Golin]

Hi Gabor,

The idea is good, but I think we need a better implementation... Something that would be valid for other archs too.

As I see it, some arch strings are static (ex. "r600" or "hexagon"), and for them, a StringSwitch is the best way.

Others, like ARM ("armv*") and Intel ("i*", "x86*"), MIPS ("mips*") would better be separate on their own static inline functions returning the Triple::ArchType, not boolean. Your new function is good, but instead of boolean, change it to Triple::ArchType, and implement it for the others that have the same pattern.

cheers,
