Craig Topper eea52429cd [AVX-512] Update vextract64x4 intrinsic upgrade test cases to use a legal immediate so they test the instruction selection correctly.

Craig Topper d0aa53b9ae [AVX-512] Add support for detecting 512-bit shuffles that contain a 128-bit subvector insertion from the lowest subvector of one of the sources.
These are best handled with a vinsert32x4 or vinsert64x2 instruction.

Craig Topper 0cda8bbf74 [AVX-512] Remove vinsert intrinsics and autoupgrade to native shufflevectors. There are some codegen problems here that I'll try to fix in future commits.

Craig Topper 4d47c6ae57 [AVX-512] Remove vextract intrinsics and autoupgrade to native shufflevectors. This unfortunately generates some really terrible code without VLX support due to v2i1 and v4i1 not being legal.
Hopefully we can improve that in future patches.

Simon Pilgrim b57dd17142 [X86][AVX512] Autoupgrade lossless i32/u32 to f64 conversion intrinsics with generic IR
Both the (V)CVTDQ2PD (i32 to f64) and (V)CVTUDQ2PD (u32 to f64) conversion instructions are lossless and can be safely represented as generic SINT_TO_FP/UINT_TO_FP calls instead of x86 intrinsics without affecting final codegen.

Craig Topper da6a63db1c [AVX-512] Remove the remaining masked shift by immediate or by single value. Autoupgrade them to recently introduced unmasked versions and a select.
After this I'll add the unmasked intrinsics to InstCombineCalls to finish making our handling of these types of shuffles consistent between AVX-512 and the legacy intrinsics.

Craig Topper b110e04851 [AVX-512] Remove masked pmovzx/pmovsx builtins and autoupgrade them to selects and native zext/sext.
This mostly reuses earlier autoupgrade support for the sse and avx equivalents. Just needed to add the code to add the select.

Elena Demikhovsky dca03bebd3 AVX-512: Changed lowering of BITCAST between i1 vectors and i8/i16/i32 integer values
Optimized lowering of BITCAST node. The BITCAST node can be replaced with COPY_TO_REG instead of KMOV.
It allows to suppress two opposite BITCAST operations and avoid redundant "movs".

Matthias Braun 152e7c8b12 VirtRegMap: Replace some identity copies with KILL instructions.
An identity COPY like this:
   %AL = COPY %AL, %EAX<imp-def>
has no semantic effect, but encodes liveness information: Further users
of %EAX only depend on this instruction even though it does not define
the full register.

Replace the COPY with a KILL instruction in those cases to maintain this
liveness information. (This reverts a small part of r238588 but this
time adds a comment explaining why a KILL instruction is useful).

Simon Pilgrim 7c2fbdc101 [X86][AVX512] Add support for masked shuffle comments
This patch adds support for including the avx512 mask register information in the mask/maskz versions of shuffle instruction comments.

This initial version just adds support for MOVDDUP/MOVSHDUP/MOVSLDUP to reduce the mass of test regenerations, other shuffle instructions can be added in due course.
