Use TableGen'erated pseudo lowering for ARM.
...
Hook up the TableGen lowering for simple pseudo instructions for ARM and
use it for a subset of the many pseudos the backend has as proof of concept.
More conversions to come.

Revert r130178. It turned out to be not the optimal path to emit complex location expressions.

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.

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.

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.
