f9568d8700 Don't diddle VRSAVE if no registers need to be added/removed from it. This
allows us to codegen functions as:

_test_rol:
        vspltisw v2, -12
        vrlw v2, v2, v2
        blr

instead of:

_test_rol:
        mfvrsave r2, 256
        mr r3, r2
        mtvrsave r3
        vspltisw v2, -12
        vrlw v2, v2, v2
        mtvrsave r2
        blr

Testcase here: CodeGen/PowerPC/vec_vrsave.ll

402504b1ba Vectors that are known live-in and live-out are clearly already marked in
the vrsave register for the caller.  This allows us to codegen a function as:

_test_rol:
        mfspr r2, 256
        mr r3, r2
        mtspr 256, r3
        vspltisw v2, -12
        vrlw v2, v2, v2
        mtspr 256, r2
        blr

instead of:

_test_rol:
        mfspr r2, 256
        oris r3, r2, 40960
        mtspr 256, r3
        vspltisw v0, -12
        vrlw v2, v0, v0
        mtspr 256, r2
        blr

939274fcfd Prefer to allocate V2-V5 before V0,V1. This lets us generate code like this:
vspltisw v2, -12
        vrlw v2, v2, v2

instead of:

        vspltisw v0, -12
        vrlw v2, v0, v0

when a function is returning a value.

8d5a894501 Codegen insertelement with constant insertion points as scalar_to_vector
and a shuffle.  For this:

void %test2(<4 x float>* %F, float %f) {
        %tmp = load <4 x float>* %F             ; <<4 x float>> [#uses=2]
        %tmp3 = add <4 x float> %tmp, %tmp              ; <<4 x float>> [#uses=1]
        %tmp2 = insertelement <4 x float> %tmp3, float %f, uint 2               ; <<4 x float>> [#uses=2]
        %tmp6 = add <4 x float> %tmp2, %tmp2            ; <<4 x float>> [#uses=1]
        store <4 x float> %tmp6, <4 x float>* %F
        ret void
}

we now get this on X86 (which will get better):

_test2:
        movl 4(%esp), %eax
        movaps (%eax), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, %xmm1
        shufps $3, %xmm1, %xmm1
        movaps %xmm0, %xmm2
        shufps $1, %xmm2, %xmm2
        unpcklps %xmm1, %xmm2
        movss 8(%esp), %xmm1
        unpcklps %xmm1, %xmm0
        unpcklps %xmm2, %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%eax)
        ret

instead of:

_test2:
        subl $28, %esp
        movl 32(%esp), %eax
        movaps (%eax), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%esp)
        movss 36(%esp), %xmm0
        movss %xmm0, 8(%esp)
        movaps (%esp), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%eax)
        addl $28, %esp
        ret

ac225ca051 Add a new way to match vector constants, which make it easier to bang bits of
different types.

Codegen spltw(0x7FFFFFFF) and spltw(0x80000000) without a constant pool load,
implementing PowerPC/vec_constants.ll:test1.  This compiles:

typedef float vf __attribute__ ((vector_size (16)));
typedef int vi __attribute__ ((vector_size (16)));
void test(vi *P1, vi *P2, vf *P3) {
  *P1 &= (vi){0x80000000,0x80000000,0x80000000,0x80000000};
  *P2 &= (vi){0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF};
  *P3 = vec_abs((vector float)*P3);
}

to:

_test:
        mfspr r2, 256
        oris r6, r2, 49152
        mtspr 256, r6
        vspltisw v0, -1
        vslw v0, v0, v0
        lvx v1, 0, r3
        vand v1, v1, v0
        stvx v1, 0, r3
        lvx v1, 0, r4
        vandc v1, v1, v0
        stvx v1, 0, r4
        lvx v1, 0, r5
        vandc v0, v1, v0
        stvx v0, 0, r5
        mtspr 256, r2
        blr

instead of (with two constant pool entries):

_test:
        mfspr r2, 256
        oris r6, r2, 49152
        mtspr 256, r6
        li r6, lo16(LCPI1_0)
        lis r7, ha16(LCPI1_0)
        li r8, lo16(LCPI1_1)
        lis r9, ha16(LCPI1_1)
        lvx v0, r7, r6
        lvx v1, 0, r3
        vand v0, v1, v0
        stvx v0, 0, r3
        lvx v0, r9, r8
        lvx v1, 0, r4
        vand v1, v1, v0
        stvx v1, 0, r4
        lvx v1, 0, r5
        vand v0, v1, v0
        stvx v0, 0, r5
        mtspr 256, r2
        blr

GCC produces (with 2 cp entries):

_test:
        mfspr r0,256
        stw r0,-4(r1)
        oris r0,r0,0xc00c
        mtspr 256,r0
        lis r2,ha16(LC0)
        lis r9,ha16(LC1)
        la r2,lo16(LC0)(r2)
        lvx v0,0,r3
        lvx v1,0,r5

        lwz r12,-4(r1)

3433141a3e Add a simple pass to make sure that all (non-library) calls to malloc and free
are visible to analysis as intrinsics.  That is, make sure someone doesn't pass
free around by address in some struct (as happens in say 176.gcc).

This doesn't get rid of any indirect calls, just ensure calls to free and malloc
are always direct.
