We enumerated the cross product Domain x Scatter, but sorted only be the
scatter key. In case there are are multiple statement instances per
scatter value, the order between statement instances of the same loop
iteration was undefined.
Propertly enumerate and sort only by the scatter value, and group the
domains using the scatter dimension again.
Thanks to Leonard Chan for the report.
In preparation for D98611, the upcoming change will need to apply additional checks to `P` and `V`,
and so this refactor paves the way for adding additional checks in a less awkward way.

This allows requesting information about the server uptime and start time. This is the first patch in a series of monitoring changes, hence it's not immediately useful. Next step is propagating the index freshness information and then probably loading metadata into the index server.

```
$ grpc_cli call localhost:50051 Monitor/MonitoringInfo ''
connecting to localhost:50051

index_age_seconds: 609568

Implement initial support for pull-based diagnostics in ClangdServer.
This is planned for LSP 3.17, and initial proposal is in
d15eb0671e/protocol/src/common/proposed.diagnostic.ts (L111).
We chose to serve the requests only when clangd has a fresh preamble
available. In case of a stale preamble we just drop the request on the
floor.
This patch doesn't plumb this to LSP layer yet, as pullDiags is still a
proposal with only an implementation in vscode.

Somewhat surprisingly, signature help is emitted as a side-effect of
computing the expected type of a function argument.
The reason is that both actions require enumerating the possible
function signatures and running partial overload resolution, and doing
this twice would be wasteful and complicated.
Change #1: document this, it's subtle :-)
However, sometimes we need to compute the expected type without having
reached the code completion cursor yet - in particular to allow
completion of designators.
eb4ab3358c did this but introduced a
regression - it emits signature help in the wrong location as a side-effect.
Change #2: only emit signature help if the code completion cursor was reached.
Currently there is PP.isCodeCompletionReached(), but we can't use it
because it's set *after* running code completion.
It'd be nice to set this implicitly when the completion token is lexed,
but ConsumeCodeCompletionToken() makes this complicated.
Change #3: call cutOffParsing() *first* when seeing a completion token.
After this, the fact that the Sema::Produce*SignatureHelp() functions
are even more confusing, as they only sometimes do that.
I don't want to rename them in this patch as it's another large
mechanical change, but we should soon.
Change #4: prepare to rename ProduceSignatureHelp() to GuessArgumentType() etc.

When GlobalISelEmitter::emitCxxPredicateFns emitted code for MI
predicates it used "PatFrag" when searching for definitions. With
this patch it will search for all "PatFrags" instead. Since PatFrag
derives from PatFrags the difference is that we now include all
definitions using PatFrags directly as well. Thus making it possible
to use GISelPredicateCode together with a PatFrags definition.
It might be noted that the matcher code was emitted also for PatFrags
in the past. But then one ended up with errors since the custom code
in testMIPredicate_MI was missing.

Fixes an issue discovered post commit in https://reviews.llvm.org/D98278
`parser::AllocateObject` and `parser::PointerObject` can be represented
as typed expressions once analyzed. This simplifies the work for parse-tree
consumers that work with typed expressions to deal with allocatable and
pointer objects such as lowering.
This change also makes it easier to add typedExpr in the future by
automatically handling nodes that have this member when possible.
Changes:
- Add a `mutable TypedExpr typedExpr` field to `parser::PointerObject` and `parser::AllocateObject`.
- Add a `parser::HasTypedExpr<T>` helper to better share code relating to typedExpr in the parse tree.
- Add hooks in `semantics::ExprChecker` for AllocateObject and PointerObject nodes, and use
ExprOrVariable on it to analyze and set the tyedExpr field during
expression analysis. This required adding overloads for `AssumedTypeDummy`.
- Update check-nullify.cpp and check-deallocate.cpp to not re-analyze the StructureComponent but to
use the typedExpr field instead.
- Update dump/unparse to use HasTypedExpr and use the typedExpr when there is one.

Lit as it exists today has three hacks that allow users to run tests earlier:
1) An entire test suite can set the `is_early` boolean.
2) A very recently introduced "early_tests" feature.
3) The `--incremental` flag forces failing tests to run first.
All of these approaches have problems.
1) The `is_early` feature was until very recently undocumented. Nevertheless it still lacks testing and is a imprecise way of optimizing test starting times.
2) The `early_tests` feature requires manual updates and doesn't scale.
3) `--incremental` is undocumented, untested, and it requires modifying the *source* file system by "touching" the file. This "touch" based approach is arguably a hack because it confuses editors (because it looks like the test was modified behind the back of the editor) and "touching" the test source file doesn't work if the test suite is read only from the perspective of `lit` (via advanced filesystem/build tricks).
This patch attempts to simplify and address all of the above problems.
This patch formalizes, documents, tests, and defaults lit to recording the execution time of tests and then reordering all tests during the next execution. By reordering the tests, high core count machines run faster, sometimes significantly so.
This patch also always runs failing tests first, which is a positive user experience win for those that didn't know about the hidden `--incremental` flag.
Finally, if users want, they can _optionally_ commit the test timing data (or a subset thereof) back to the repository to accelerate bots and first-time runs of the test suite.

This patch adds support for reverse loop vectorization.
It is possible to vectorize the following loop:
```
for (int i = n-1; i >= 0; --i)
a[i] = b[i] + 1.0;
```
with fixed or scalable vector.
The loop-vectorizer will use 'reverse' on the loads/stores to make
sure the lanes themselves are also handled in the right order.
This patch adds support for scalable vector on IRBuilder interface to
create a reverse vector. The IR function
CreateVectorReverse lowers to experimental.vector.reverse for scalable vector
and keedp the original behavior for fixed vector using shuffle reverse.

This pass runs in any situations but we skip it when it is not O0 and the
function doesn't have optnone attribute. With -O0, the def of shape to amx
intrinsics is near the amx intrinsics code. We are not able to find a
point which post-dominate all the shape and dominate all amx intrinsics.
To decouple the dependency of the shape, we transform amx intrinsics
to scalar operation, so that compiling doesn't fail. In long term, we
should improve fast register allocation to allocate amx register.
