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".

Craig Topper 00d34ed64f [AVX-512] Don't let ExeDependencyFix pass convert VPANDD/Q to VPANDPS/PD unless DQI instructions are supported. Same for ANDN, OR, and XOR.

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.
