2b21fbaf11 Remove pattern fragments for v32i8, v16i16, v8i32, v16i8, v8i16, and v4i32 loads. All integer vector loads are promoted to v2i64 or v4i64 so these pattern fragments can never match. Fix or remove patterns that used these fragments.

8f35c13842 Improve 256-bit shuffle splitting to allow 2 sources in each 128-bit lane. As long as only a single lane of the source is used in the lane in the destination. This makes the splitting match much closer to what happens with 256-bit shuffles when AVX is disabled and only 128-bit XMM is allowed.

31867660cb Add a CoveredBySubRegs property to Register descriptions.
When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.

0b94b5f52b Fix 11769.
In CanXFormVExtractWithShuffleIntoLoad we assumed that EXTRACT_VECTOR_ELT can be later handled by the DAGCombiner.
However, in some cases on AVX, the EXTRACT_VECTOR_ELT is legalized to EXTRACT_SUBVECTOR + EXTRACT_VECTOR_ELT, which
currently is not handled by the DAGCombiner. In this patch I added a check that we only extract from the XMM part.

cc6165695f [AVX] Optimize x86 VSELECT instructions using SimplifyDemandedBits.
We know that the blend instructions only use the MSB, so if the mask is
sign-extended then we can convert it into a SHL instruction. This is a
common pattern because the type-legalizer sign-extends the i1 type which
is used by the LLVM-IR for the condition.

Added a new optimization in SimplifyDemandedBits for SIGN_EXTEND_INREG -> SHL.
