The `sne Dst, Src1, Src2/Imm` pseudo instruction sets register `Dst` to
1 if register `Src1` is not equal to `Src2/Imm` and to 0 otherwise.

The `sle/sleu Dst, Src1, Src2/Imm` pseudo instructions set register
`Dst` to 1 if register `Src1` is less than or equal `Src2/Imm` and
to 0 otherwise.

This will match the changes mlir.llvm.org side.

Extract common code to a function. To prepare for
adding an option for CUDA/HIP host and device only

SplitsOpsAndApply will take care of any needed splitting correctly.
All that we need to check is that the vector element count is a
power of 2.

Make sure it is a multiple of 2 bytes as specified in the LangRef.

D75801 removed the last and only user of this option, so we can
drop it now. The original idea behind this was to only run expensive
transforms under -O3, but apart from the one known bits transform,
this has never really taken off. I believe nowadays the recommendation
is to put expensive transforms in AggressiveInstCombine instead,
though that isn't terribly popular either :)

The TTI hooks aren't converted. I also think the intrinsics should
have mandatory alignment and never return MaybeAlign.

For folding pattern `x-(fma y,z,u*v) -> (fma -y,z,(fma -u,v,x))`, if
`yz` is 1, `uv` is -1 and `x` is -0, sign of result would be changed.

Finally resurrecting D56506 and want to improve test coverage.

Summary:
Avoid blind cast from Operator to ExtractElementInst in
computeKnownBitsFromOperator. This resulted in some crashes
in downstream fuzzy testing. Instead we use getOperand directly
on the Operator when accessing the vector/index operands.

Haven't seen any problems with InsertElement and ShuffleVector,
but I believe those could be used in constant expressions as well.
So the same kind of fix as for ExtractElement was also applied for
InsertElement.

When it comes to ShuffleVector we now simply bail out if a dynamic
cast of the Operator to ShuffleVectorInst fails. I've got no
reproducer indicating problems for ShuffleVector, and a fix would be
slightly more complicated as getShuffleDemandedElts is involved.

We need to insert into the Visited set at the same time we insert
into the worklist. Otherwise we may end up pushing the same
instruction to the worklist multiple times, and only adding it to
the visited set later.

Summary:
This removes the static pass registration, and also cleans up some lingering technical debt.

For the common case, we will only insert one value into this map.

We can use the parent MCObjectFileInfo::Ctx which has the same value.

This type was already well designed - having a protected destructor, and
derived classes being final/public non-virtual destructors, the type
couldn't be destroyed polymorphically & accidentally cause slicing.

This reverts commit 736385c0.

DebugUtils.h seems like a more appropriate home for these.

Fix memref type doc comment to state that -1 indicates a dynamically
shaped dimension and not any negative number.

This cases produces a psadbw that doesn't need to be widened or
extracted so takes a slightly different code path in
combineLoopSADPattern.

This reverts commit 73cf8abb.

It is already assumed to be nonnull by the code calling diagAppertainsToDecl.

We often widen xmm/ymm vectors to ymm/zmm by insertion into an undef base vector. By letting getTargetShuffleAndZeroables track the undef elts we can help avoid a lot of unnecessary cross-lane shuffles.
