[MLIR][Affine] Remove restriction in slice validity check on symbols (#180709)
Remove restriction in affine analysis utility for checking slice
validity. This was unnecessarily bailing out still after the underlying
methods were extended. This update enables fusion of affine nests with
symbolic bounds.

[Flang][OpenMP] Fix visibility of user-defined reductions for derived types and module imports (#180552)
User-defined reductions declared in a module were not visible to
programs that imported the module via USE statements, causing valid code
to be incorrectly rejected. The reduction identifier defined in the
module scope wasn't being found during semantic analysis of the main
program.
Ref:
OpenMP Spec 5.1
_"If a directive appears in the specification part of a module then the
behavior is as if that directive,
with the variables, types and procedures that have PRIVATE accessibility
omitted, appears in the
specification part of any compilation unit that references the module
unless otherwise specified "_

[AMDGPU] Introduce asyncmark/wait intrinsics
Asynchronous operations are memory transfers (usually between the global memory
and LDS) that are completed independently at an unspecified scope. A thread that
requests one or more asynchronous transfers can use async marks to track their
completion. The thread waits for each mark to be completed, which indicates that
requests initiated in program order before this mark have also completed.
For now, we implement asyncmark/wait operations on pre-GFX12 architectures that
support "LDS DMA" operations. Future work will extend support to GFX12Plus
architectures that support "true" async operations.

diff: Report I/O errors in Stone algorithm
In the legacy Stone algorithm, we do a first pass over the files to
check if they're identical before we start diffing them. That code
would correctly set the exit status if an I/O error was encountered,
but would not emit an error message. Do so.

diff: Fix pagination leak
* Drop an unnecessary variable and rename pidfd to procd.
* Rewinding stdout serves no purpose, so stop doing it.
* Don't bother freeing memory or setting the global status right
before erroring out.
* Error out if dup(2) or dup2(2) fail.
* In the unlikely case that our pipe is equal to stdout, we need to
record that information so we don't close it when cleaning up.
* Don't bother closing a descriptor before dup2(2)ing to it.
* Don't forget to close the the process descriptor after reaping the
child process.

[clang] Ensure -mno-outline adds attributes
Before this change, `-mno-outline` and `-moutline` only controlled the
pass pipelines for the invoked compiler/linker.
The drawback of this implementation is that, when using LTO, only the
flag provided to the linker invocation is honoured (and any files which
individually use `-mno-outline` will have that flag ignored).
This change serialises the `-mno-outline` flag into each function's
IR/Bitcode, so that we can correctly disable outlining from functions in
files which disabled outlining, without affecting outlining choices for
functions from other files. This matches how other optimisation flags
are handled so the IR/Bitcode can be correctly merged during LTO.
[clang] Add clang::nooutline Attribute
This change:
- Adds a `[[clang::nooutline]]` function attribute for C and C++. There
is no equivalent GNU syntax for this attribute, so no `__attribute__`
syntax.
- Uses the presence of `[[clang::nooutline]]` to add the `nooutline`
attribute to IR function definitions.
- Adds test for the above.
The `nooutline` attribute disables both the Machine Outliner (enabled at
Oz for some targets), and the IR Outliner (disabled by default).

[AMDGPU] Asynchronous loads from global/buffer to LDS on pre-GFX12 (#180466)
The existing "LDS DMA" builtins/intrinsics copy data from global/buffer
pointer to LDS. These are now augmented with their ".async" version,
where the compiler does not automatically track completion. The
completion is now tracked using explicit mark/wait intrinsics, which
must be inserted by the user. This makes it possible to write programs
with efficient waits in software pipeline loops. The program can now
wait for only the oldest outstanding operations to finish, while
launching more operations for later use.
This change only contains the new names of the builtins/intrinsics,
which continue to behave exactly like their non-async counterparts. A
later change will implement the actual mark/wait semantics in
SIInsertWaitcnts.
This is part of a stack split out from #173259:
- #180467
- #180466
