d94bc549fc Add FastEmitInst_ii for the arm fast isel generator. It doesn't use it, but
if it ever did it needs the def machinery.

5de5d4b6d0 Materialize GA addresses with movw + movt pairs for Darwin in PIC mode. e.g.
movw    r0, :lower16:(L_foo$non_lazy_ptr-(LPC0_0+4))

LPC0_0:
        add     r0, pc, r0

It's not yet enabled by default as some tests are failing. I suspect bugs in
down stream tools.

value type, so there is no point in passing it around using

low impact change instead.
