800f12df1e Can't fold loads into alias vector SSE ops used for scalar operation. The load 
address has to be 16-byte aligned but the values aren't spilled to 128-bit
locations.

f3f69decca Implement a TODO: have the legalizer canonicalize a bunch of operations to 
one type (v4i32) so that we don't have to write patterns for each type, and
so that more CSE opportunities are exposed.

to write one pattern for vector stores instead of 4.

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);
}

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.

d2cfb7a670 We have an assertion that checks that we do not encode null values into the 
.bc file if they are supposed to be implicit.  This is cool, except that it
checked *after* constant expr folding: improving constant expr folding could
cause the .bc reader to assert out on old .bc files.  Move the check so that
it checks all simple constants, but no constantexprs.

5ced1d812e - movlp{s|d} and movhp{s|d} support. 
- Normalize shuffle nodes so result vector lower half elements come from the
  first vector, the rest come from the second vector. (Except for the
  exceptions :-).
- Other minor fixes.

e2ed057562 Lower vperm(x,y, mask) -> shuffle(x,y,mask) if mask is constant. This allows 
us to compile oh-so-realistic stuff like this:

 vec_vperm(A, B, (vector unsigned char){14});

to:
        vspltb v0, v0, 14

instead of:

        vspltisb v0, 14
        vperm v0, v2, v1, v0

1d5a8cca00 Handle canonical form of e.g. 
vector_shuffle v1, v1, <0, 4, 1, 5, 2, 6, 3, 7>

This is turned into
vector_shuffle v1, <undef>, <0, 0, 1, 1, 2, 2, 3, 3>
by dag combiner.

It would match a {p}unpckl on x86.
