4a1cd9c61e The BFS scheduler is apparently nondeterminstic (causes many llvmgcc bootstrap 
miscompares).  Switch RISC targets to use the list-td scheduler, which isn't.

017dcc6e55 Now generating perfect (I think) code for "vector set" with a single non-zero 
scalar value.

e.g.
        _mm_set_epi32(0, a, 0, 0);
==>
	movd 4(%esp), %xmm0
	pshufd $69, %xmm0, %xmm0

        _mm_set_epi8(0, 0, 0, 0, 0, a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
==>
	movzbw 4(%esp), %ax
	movzwl %ax, %eax
	pxor %xmm0, %xmm0
	pinsrw $5, %eax, %xmm0

fedced7bc3 Fix a really subtle and obnoxious memory bug that caused issues with an 
llvm-gcc4 boostrap.  Whenever a node is deleted by the dag combiner, it
*must* be returned by the visit function, or the dag combiner will not
know that the node has been processed (and will, e.g., send it to the
target dag combine xforms).

8117f9a40e If we can convert the return pointer type into an integer that IntPtrType 
can be converted to losslessly, we can continue the conversion to a direct call.

39623daef6 - Added support to turn "vector clear elements", e.g. pand V, <-1, -1, 0, -1> 
to a vector shuffle.
- VECTOR_SHUFFLE lowering change in preparation for more efficient codegen
of vector shuffle with zero (or any splat) vector.

44f1f09b4e Turn a VAND into a VECTOR_SHUFFLE is applicable. 
DAG combiner can turn a VAND V, <-1, 0, -1, -1>, i.e. vector clear elements,
into a vector shuffle with a zero vector. It only does so when TLI tells it
the xform is profitable.

72cd9a9439 Handle v2i64 BUILD_VECTOR custom lowering correctly. v2i64 is a legal type, 
but i64 is not. If possible, change a i64 op to a f64 (e.g. load, constant)
and then cast it back.
