5de5d4b6d0 Materialize GA addresses with movw + movt pairs for Darwin in PIC mode. e.g.
movw    r0, :lower16:(L_foo$non_lazy_ptr-(LPC0_0+4))
        movt    r0, :upper16:(L_foo$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.

- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

e4e5e2aae7 Add support to the ARM MC infrastructure to support mcr and friends. This requires supporting
the symbolic immediate names used for these instructions, fixing their pretty-printers, and
adding proper encoding information for them.

With this, we can properly pretty-print and encode assembly like:
	mrc p15, #0, r3, c13, c0, #3

Fixes <rdar://problem/8857858>.

5f3e2be7c9 When updating a tSpill/tRestore instruction to be a tSTRr/tLDRr, correctly
set up the source operands. The original instr has an immediate operand that
should be replaced with the frame reg operand rather than just adding the
reg operand. Previously, the instruction ended up with too many operands
causing an assert() when adding the default predicate. rdar://8825456

7597212abc Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

fef9ff4922 Add a FIXME and two asserts for now in the ARMAsmParser when it sees .code 16 or
.code 32 if the TargetMachine's isThumb() boolean does not match.  The correct
fix is to switch ARM subtargets at that point and is tracked by rdar://8856789
which is bigger task.

650b7d76af JimG sez: "The value-kinds look like masks, but they're not consistently used
that way, unfortunately. If you want to change them to work additively instead
of a one-variant-kind-per-symbolref, that's great and I completely agree it's
worth doing, but it really should be a separate patch. Until then, this isn't
correct."

So I am reverting this bit until a more opportune time.
