Significantly improve handling of vectors that are live across basic blocks,
...
handling cases where the vector elements need promotion, expansion, and when
the vector type itself needs to be decimated.

When building a VVECTOR_SHUFFLE node from extract_element operations, make
...
sure to build it as SHUFFLE(X, undef, mask), not SHUFFLE(X, X, mask).
The later is not canonical form, and prevents the PPC splat pattern from
matching. For a particular splat, we go from generating this:
li r10, lo16(LCPI1_0)
lis r11, ha16(LCPI1_0)
lvx v3, r11, r10
vperm v3, v2, v2, v3
to generating:
vspltw v3, v2, 3

Turn a series of extract_element's feeding a build_vector into a
...
vector_shuffle node. For this:
void test(__m128 *res, __m128 *A, __m128 *B) {
*res = _mm_unpacklo_ps(*A, *B);
}
we now produce this code:
_test:
movl 8(%esp), %eax
movaps (%eax), %xmm0
movl 12(%esp), %eax
unpcklps (%eax), %xmm0
movl 4(%esp), %eax
movaps %xmm0, (%eax)
ret
instead of this:
_test:
subl $76, %esp
movl 88(%esp), %eax
movaps (%eax), %xmm0
movaps %xmm0, (%esp)
movaps %xmm0, 32(%esp)
movss 4(%esp), %xmm0
movss 32(%esp), %xmm1
unpcklps %xmm0, %xmm1
movl 84(%esp), %eax
movaps (%eax), %xmm0
movaps %xmm0, 16(%esp)
movaps %xmm0, 48(%esp)
movss 20(%esp), %xmm0
movss 48(%esp), %xmm2
unpcklps %xmm0, %xmm2
unpcklps %xmm1, %xmm2
movl 80(%esp), %eax
movaps %xmm2, (%eax)
addl $76, %esp
ret
GCC produces this (with -fomit-frame-pointer):
_test:
subl $12, %esp
movl 20(%esp), %eax
movaps (%eax), %xmm0
movl 24(%esp), %eax
unpcklps (%eax), %xmm0

SelectionDAGISel can now natively handle Switch instructions, in the same
...
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary
search tree of basic blocks. The new approach has several advantages:
it is faster, it generates significantly smaller code in many cases, and
it paves the way for implementing dense switch tables as a jump table by
handling switches directly in the instruction selector.
This functionality is currently only enabled on x86, but should be safe for
every target. In anticipation of making it the default, the cfg is now
properly updated in the x86, ppc, and sparc select lowering code.
