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.

dec28ceb02 fix PR8514, a bug where the "heroic" transformation of shift/and 
into and/shift would cause nodes to move around and a dangling pointer
to happen.  The code tried to avoid this with a HandleSDNode, but 
got the details wrong.

d754041493 fix PR8961 - a fast isel miscompilation where we'd insert a new instruction 
after sext's generated for addressing that got folded.  Previously we compiled
test5 into:

_test5:                                 ## @test5
## BB#0:
        movq    -8(%rsp), %rax          ## 8-byte Reload
        movq    (%rdi,%rax), %rdi
        addq    %rdx, %rdi
        movslq  %esi, %rax
        movq    %rax, -8(%rsp)          ## 8-byte Spill
        movq    %rdi, %rax
        ret

which is insane and wrong.  Now we produce:

_test5:                                 ## @test5
## BB#0:
	movslq	%esi, %rax
	movq	(%rdi,%rax), %rax
	addq	%rdx, %rax
	ret

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
