72f2c7d2ee Do actual DCE in LoopUnroll (try 2) 
Recommitting after addressing a missed review comment, and updating an aarch64 test I'd missed.

LoopUnroll does a limited DCE pass after unrolling, but if you have a chain of dead instructions, it only deletes the last one. Improve the code to recursively delete all trivially dead instructions.

15058e16a1 AMDGPU: Fix assert when rewriting saddr d16 loads 
moveOperands does not handle moving tied operands since it would
generally have to fixup the tied operand references. Avoid the assert
by untying and retying after the modification. These in place
modifications really aren't managable.

7a6506cfad [NFC][X86][MCA] Add sudo-zero-idiom vperm2f128/vperm2i128 tests - don't break deps 
While btver2 model states that this pattern is a zero-cycle zero-idiom
on Jaguar, it does not appear to be the case on Znver3,
here it measures as not being recognized as dep-breaking zero-idiom,
let alone a zero-cycle one.

658d86d1c9 Revert "Do actual DCE in LoopUnroll" 
This reverts commit 9d1a61e695eb01298e26c76867d65592f1e1968c.

I'd missed some review feedback, and had missed updating an aarch64 test.  Reverting while I fix both.
