[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.

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".

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).

[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.
