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).

Craig Topper f7bf6de0af [AVX512] Remove and autoupgrade a duplicate set of 512-bit masked shift intrinsics. 
I'm not sure if clang ever used these builtin names or not.

Michael Kuperstein 3e3652aef2 Recommit r274692 - [X86] Transform setcc + movzbl into xorl + setcc 
xorl + setcc is generally the preferred sequence due to the partial register
stall setcc + movzbl suffers from. As a bonus, it also encodes one byte smaller.
This fixes PR28146.

The original commit tried inserting an 8bit-subreg into a GR32 (not GR32_ABCD)
which was not appreciated by fast regalloc on 32-bit.

Elena Demikhovsky ad0a56f3da Re-commit of 274613. 
The prev commit failed on compilation.
A minor change in one pattern in lib/Target/X86/X86InstrAVX512.td fixes the failure.

Elena Demikhovsky 5a4f2476fd AVX-512: Optimization for patterns with i1 scalar type 
The patch removes redundant kmov instructions (not all, we still have a lot of work here) and redundant "and" instructions after "setcc".
I use "AssertZero" marker between X86ISD::SETCC node and "truncate" to eliminate extra "and $1" instruction.
I also changed zext, aext and trunc patterns in the .td file. It allows to remove extra "kmov" instruictions.

This patch fixes https://llvm.org/bugs/show_bug.cgi?id=28173.

Fast ISEL mode is not supported correctly for AVX-512. ICMP/FCMP scalar instruction should return result in k-reg. It will be fixed in one of the next patches. I redirected handling of "cmp" to the DAG builder mode. (The code looks worse in one specific test case, but without this fix the new patch fails).
