[PATCH] [ARM] Use symbolic register names in .cfi directives only with IAS (PR19110)

This is a follow-up to r203635. Saleem pointed out that since symbolic register
names are much easier to read, it would be good if we could turn them off only
when we realle need to because we're using an external assembler.
It might seem more natural to make useDwarfRegNumForCFI() virtual, but since that gets called a bunch of times during asm emission, i went for setting the flag when changing IAS mode instead.
Please take a look!
