Daniel Dunbar 7ed455990d McARM: Always keep an offset expression, if used (instead of assuming == 0 if used but not present), and simplify logic. 
Also, clean up various non-sensicalisms in isMemModeRegThumb() and isMemModeImmThumb().

Eric Christopher 542f8a5221 The stub routine that we're calling uses test and so clobbers 
the flags.

Chris Lattner ea4e983d70 minor change to rafael's recent patches: if something is 
constant but requires a unique address, we can still put it in a
readonly section, just not a mergable one.

Kalle Raiskila 06c6d5cdb6 Split up RotateShift itinerary in SPU. 
'rotq*' and 'shlq*' instructions go to the odd pipeline,
wheras the inter-vector equivalents 'rot*', 'shl*' go 
to the even.

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.

Chris Lattner 35a2e65bcb 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.

Evan Cheng d4a5c05c97 Completed :lower16: / :upper16: support for movw / movt pairs on Darwin. 
- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

Chris Lattner 0c34cb429e 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
