774bdd598c Do not endian swap split vector loads. This fixes UnitTests/Vector/sumarray-dbl on PPC. 
Now all UnitTests/Vector/* tests pass on PPC.

0e7da656a7 Remove dead *extloads. This allows us to codegen vector.ll:test_extract_elt 
to:

test_extract_elt:
        alloc r3 = ar.pfs,0,1,0,0
        adds r8 = 12, r32
        ;;
        ldfs f8 = [r8]
        mov ar.pfs = r3
        br.ret.sptk.many rp

instead of:

test_extract_elt:
        alloc r3 = ar.pfs,0,1,0,0
        adds r8 = 28, r32
        adds r9 = 24, r32
        adds r10 = 20, r32
        adds r11 = 16, r32
        ;;
        ldfs f6 = [r8]
        ;;
        ldfs f6 = [r9]
        adds r8 = 12, r32
        adds r9 = 8, r32
        adds r14 = 4, r32
        ;;
        ldfs f6 = [r10]
        ;;
        ldfs f6 = [r11]
        ldfs f8 = [r8]

c3be332547 Delete dead loads in the dag. This allows us to compile 
vector.ll:test_extract_elt2 into:

_test_extract_elt2:
        lfd f1, 32(r3)
        blr

instead of:

_test_extract_elt2:
        lfd f0, 56(r3)
        lfd f0, 48(r3)
        lfd f0, 40(r3)
        lfd f1, 32(r3)
        lfd f0, 24(r3)
        lfd f0, 16(r3)

e05a1ec544 Scalarized vector stores need not be legal, e.g. if the vector element type 
needs to be promoted or expanded.  Relegalize the scalar store once created.

95d358dbdb Implement an item from the readme, folding vcmp/vcmp. instructions with 
identical instructions into a single instruction.  For example, for:

void test(vector float *x, vector float *y, int *P) {
  int v = vec_any_out(*x, *y);
  *x = (vector float)vec_cmpb(*x, *y);
  *P = v;
}

we now generate:

_test:
        mfspr r2, 256
        oris r6, r2, 49152
        mtspr 256, r6
        lvx v0, 0, r4
        lvx v1, 0, r3
        vcmpbfp. v0, v1, v0
        mfcr r4, 2
        stvx v0, 0, r3
        rlwinm r3, r4, 27, 31, 31
        xori r3, r3, 1
        stw r3, 0(r5)
        mtspr 256, r2
        blr

instead of:

_test:
        mfspr r2, 256
        oris r6, r2, 57344
        mtspr 256, r6
        lvx v0, 0, r4
        lvx v1, 0, r3
        vcmpbfp. v2, v1, v0
        mfcr r4, 2
***     vcmpbfp v0, v1, v0
        rlwinm r4, r4, 27, 31, 31
        stvx v0, 0, r3
        xori r3, r4, 1
        stw r3, 0(r5)
        mtspr 256, r2
        blr

f9e5ac8c9a Final bugfix for PR724. GCC won't inline varargs functions, so use one to 
validate the prototype of intrinsic functions.  This prevents GCC from going
crazy and inlining too much stuff, eventually running out of memory.

7ae6895610 When emitting code for the verifier, instead of emitting each case statement 
independently, batch up checks so that identically typed intrinsics share
verifier code.  This dramatically reduces the size of the verifier function,
which should help avoid GCC running out of memory compiling Verifier.cpp.

handling cases where the vector elements need promotion, expansion, and when
the vector type itself needs to be decimated.

9ebe75e915 Change SSE pack operation definitions to fit what the intrinsics expected.
