Move parseSubArch to ARMTargetParser. NFC

Browse Source 
Using getCanonicalArchName() is the right way to parse ARM arch names.

Mapping ARMTargetParser IDs to Triple Arch IDs is temporary, until they
are merged into a TargetDescription class.

This was the last LLVM FIXME to move things to ARMTargetParser. Now on
to Clang and beyond.
