First step toward making use of canLowerByDroppingEvenElements to match chains of PACKSS/PACKUS for compaction shuffles.
At the moment we still only match a single stage but the MatchPACK is now more general.
Summary:
VSCode tasks are updated to the latest supported versions: deprecated
values are removed and replaced by their new counterparts.

This allows the MVE VPT Block insertion pass to remove VPNOTs in
order to create more complex VPT blocks such as TE, TEET, TETE, etc.
Differential Revision: https://reviews.llvm.org/D75993
VPTMaskValue was using the "instruction" encoding to represent the masks
(= the same encoding as the one used by the instructions in an object file),
but it is only used to build MCOperands, so it should use the MCOperand
encoding of the masks, which is slightly different.

Summary:
It is used by code completion and signature help. Code completion
already uses a special no-compile mode for missing preambles, so this change is
a no-op for that.
As for signature help, it already blocks for a preamble and missing it implies
clang has failed to parse the preamble and retrying it in signature help likely
will fail again. And even if it doesn't, request latency will be too high to be
useful as parsing preambles is expensive.

Summary:
Aggregate types containing scalable vectors aren't supported and as far
as I can tell this pass is mostly concerned with optimisations on
aggregate types, so the majority of this pass isn't very useful for
scalable vectors.
This patch modifies SROA such that mem2reg is run on allocas with
scalable types that are promotable, but nothing else such as slicing is
done.
The use of TypeSize in this pass has also been updated to be explicitly
fixed size. When invoking the following methods in DataLayout:
* getTypeSizeInBits
* getTypeStoreSize
* getTypeStoreSizeInBits
* getTypeAllocSize
we now called getFixedSize on the resultant TypeSize. This is quite an
extensive change with around 50 calls to these functions, and also the
first change of this kind (being explicit about fixed vs scalable
size) as far as I'm aware, so feedback welcome.
A test is included containing IR with scalable vectors that this pass is
able to optimise.

PTEST/TESTP sets EFLAGS as:
TESTZ: ZF = (Op0 & Op1) == 0
TESTC: CF = (~Op0 & Op1) == 0
TESTNZC: ZF == 0 && CF == 0
If we are inverting the 0'th operand of a PTEST/TESTP instruction we can adjust the comparisons to correct handle the inversion implicitly.
Additionally, for "TESTZ" (ZF) cases, the allones case, PTEST(X,-1) can be simplified to PTEST(X,X).
We can expand this for the TESTZ(X,~Y) pattern and also handle KTEST/KORTEST in the future.

Make sure we do not assert on value types not being
simple in getFauxShuffleMask when analysing operations

Summary:
On most hosts we were running shell commands with an empty environment.
The only exception was windows, which was inheriting the host enviroment
mostly by accident.
Running the commands in an empty environment does not sound like a
sensible default, so this patch changes Host::RunShellCommand to inherit
the host environment. This impacts both commands run via
SBPlatform::Run (in case of host platforms), as well as the "platform
shell" CLI command.

Summary:
This revision adds support for auto-generating pass documentation, replacing the need to manually keep Passes.md up-to-date. This matches the behavior already in place for dialect and interface documentation.
Differential Revision: https://reviews.llvm.org/D76660
This revision adds support for generating utilities for passes such as options/statistics/etc. that can be inferred from the tablegen definition. This removes additional boilerplate from the pass, and also makes it easier to remove the reliance on the pass registry to provide certain things(e.g. the pass argument).
Differential Revision: https://reviews.llvm.org/D76659
This removes the need to statically register conversion passes, and also puts all of the conversions within one centralized file.
Differential Revision: https://reviews.llvm.org/D76658
This generates a Passes.td for all of the dialects that have transformation passes. This removes the need for global registration for all of the dialect passes.
Differential Revision: https://reviews.llvm.org/D76657
This will greatly simplify a number of things related to passes:
* Enables generation of pass registration
* Enables generation of boiler plate pass utilities
* Enables generation of pass documentation
This revision focuses on adding the basic structure and adds support for generating the registration for passes in the Transforms/ directory. Future revisions will add more support and move more passes over.

Summary:
It prevents code completion entirely in affected method bodies.
The main reason it's turned on is for compatibility with headers, so we turn it
off for the main file only. This is allowed because it's a compatible langopt.

Currently ConstantRange::binaryAnd/binaryOr results are too pessimistic
for single element constant ranges.
If both operands are single element ranges, we can use APInt's AND and
OR implementations directly.
Note that some other binary operations on constant ranges can cover the
single element cases naturally, but for OR and AND this unfortunately is
not the case.

Summary:
The commit provides a single method to build affine maps with zero or more
results. Users of mlir::AffineMap previously had to dispatch between two methods
depending on the number of results.
At the same time, this commit fixes the method for building affine map with zero
results that was previously ignoring its `symbolCount` argument.
