6db5e91e16 Implement splitting support for store, allowing us to compile: 
%f8 = type <8 x float>

define void @test_f8(%f8* %P, %f8* %Q, %f8* %S) {
	%p = load %f8* %P		; <%f8> [#uses=1]
	%q = load %f8* %Q		; <%f8> [#uses=1]
	%R = add %f8 %p, %q		; <%f8> [#uses=1]
	store %f8 %R, %f8* %S
	ret void
}

into:

_test_f8:
	movaps	16(%rdi), %xmm0
	addps	16(%rsi), %xmm0
	movaps	(%rdi), %xmm1
	addps	(%rsi), %xmm1
	movaps	%xmm0, 16(%rdx)
	movaps	%xmm1, (%rdx)
	ret

e93a775a4d Fix a significant code quality regression I introduced on PPC64 quite 
a while ago.  We now produce:

_foo:
	mflr r0
	std r0, 16(r1)
	ld r2, 16(r1)
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

instead of:

_foo:
	mflr r0
	std r0, 16(r1)
	lis r0, 0
	ori r0, r0, 16
	ldx r2, r1, r0
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

for:

void foo(void **X) {
  *X = __builtin_return_address(0);
}

on ppc64.

        cmplw cr0, r2, r4
        bne cr0, LBB1_1 ; bb
LBB1_2: ; return
        blr 

to:
