Anton Korobeynikov e7410dd0d5 Preliminary support for ARM frame save directives emission via MI flags. 
This is just very first approximation how the stuff should be done
(e.g. ARM-only for now). More to follow.

Evan Cheng dfce83c8f5 Materialize GA addresses with movw + movt pairs for Darwin in PIC mode. e.g. 
movw    r0, :lower16:(L_foo$non_lazy_ptr-(LPC0_0+4))
        movt    r0, :upper16:(L_foo$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.

Anton Korobeynikov 62acecd7e1 Model operand restrictions of mul-like instructions on ARMv5 via 
earlyclobber stuff. This should fix PRs 2313 and 8157.

Unfortunately, no testcase, since it'd be dependent on register
assignments.
