Philip Reames 653fa0b46a 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.

Mitch Phillips c17ac8432e [GWP-ASan] Migrate lit tests from old Scudo -> Standalone. 
This removes one of the last dependencies on old Scudo, and should allow
us to delete the old Scudo soon.

Ian Bearman 0816b96a10 Allow same memory space for SRC and DST of dma_start operations 
This change allows the SRC and DST of dma_start operations to be located in the
    same memory space. This applies to both the Affine dialect and Memref dialect
    versions of these Ops. The documention has been updated to reflect this by
    explicitly stating overlapping memory locations are not supported (undefined
    behavior).

River Riddle 3fef2d26a3 [mlir][NFC] Move passes in test/lib/Transforms/ to a directory that mirrors what they test 
test/lib/Transforms/ has bitrot and become somewhat of a dumping grounds for testing pretty much any part of the project. This revision cleans this up, and moves the files within to a directory that reflects what is actually being tested.

Matt Arsenault c7cff08f79 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.

[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.
