TargetParser does not handle armv7l in parseArchProfile()

Summary

ARM v7L is what chromebooks have. It matches the 'A' profile of ARM architecture. I realised this when working on TargetInfo and ACLE macros. Tests are intentionally not present in this patch. Should be tested by clang.

That was fast! Thanks :)
