Enabling and using dwarf exceptions seems like an easier path to take, than to make the COFF/ARM backend output EHABI directives. Previously, no EH model was enabled at all on this target. There's no point in setting UseIntegratedAssembler to false since GNU binutils doesn't support Windows on ARM, and since we don't need to support external assembler, we don't need to use register numbers in cfi directives.
