javascript: Read fields of ObjectBlock lazily
When linking a module with a large dependency footprint too much of the
object files were forced during linking. This lead to a large amount of
memory taken up by thunks which would never be forced
On the PartialDownsweep test this halves the memory required (from 25G
to 13G).
Towards #25324

Rewrite partitionByWorkerSize to avoid pattern match checker bug
With `-g3` the pattern match checker would warn about these incomplete
patterns. This affects the debug_info builds on CI.
```
Pattern match(es) are non-exhaustive
In an equation for ‘go’:
Patterns of type ‘[a]’, ‘[a]’, ‘[SpecFailWarning]’ not matched:
(_:_) _ _
|
2514 | go [] small warnings = (small, warnings)
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^...
```

Remove the wrapper/coercion-passing logic for submultiplicity checks
Instead, we use a dedicated DelayedError, which is emitted
systematically on submultiplicity checks, but is suppressed if we can
indeed solve the submultiplicity constraint with a reflexivity
coercion.
This way, we don't have to return anything from `tcSubMult`, which now
looks like a regular constraint check, the rest is implementation
detail. This removes all of the strange boilerplate that I'd been
struggling with under the previous implementation. Even if
submultiplicity checks are not properly constraints, this way it's
contained entirely within a `WantedConstraint`. Much more pleasant.
Closes #25128.

user's guide: update docs for X86 CPU flags
This commit updates the section of the user's guide pertaining to
X86 feature flags with the following changes:
- the NCG backend now supports SIMD, so remove all text
that says the contrary,
- the LLVM backend does not "automatically detect" features,
so remove any text that makes that claim.

the whole testsuite.

Handle exceptions from IO manager backend
If an IO manager backend throws, it will not actually have registered
the file descriptor. However, at that point, the IO manager state was
already updated to assume the file descriptor is being tracked, leading
to errors and an eventual deadlock down the line as documented in the
issue #21969.
The fix for this is to undo the IO manager state change in case the
backend throws (just as we already do when the backend signals that the
file type is not supported). The exception then bubbles up to user code.
That way we make sure that
1. the bookkeeping state of the IO manager is consistent with the
actions taken by the backend, even in the presence of unexpected
failures, and
2. the error is not silent and visible to user code, making failures
easier to debug.

Put RdrName in the foExt field of FieldOcc
The main purpose of this commit is to rip RdrName out of FieldOcc, in
accordance with #21592, and as a side note it has simplified the method
we use to deal with ambiguity somewhat.
To do the first, we make FieldOccs store (LIdP p) instead of always
storing Located RdrName, and moved the readername to the extension
points where necessary.
For the second, well, we just turn an ambiguous RdrName into a unbound
Name through mkUnboundName. Later during disambiguateRecordBinds of the
type checking phase, we will try and do type-directed disambiguation based
on the rdrName field (for now), so this hack works out fine.
See Note [Ambiguous FieldOcc in record updates] for more details.
There are two additional minor changes in this commit:
* The HsRecSel constructor of HsExpr has been moved to the extension
constuctors, since its really GHC specific.
* HsProjection no longer has a Located DotFieldOcc as a field, but just a
regular DotFieldOcc, since DotFieldOcc already wraps a located
FieldLabelString

driver: bail out when -fllvm is passed to GHC not configured with LLVM
This patch makes GHC bail out with an proper error message when it's
not configured with LLVM but users attempt to pass -fllvm, see #25011
and added comment for details.
Fixes #25011

Consider Wanteds with rewriters as insoluble
This MR fixes #25325
See GHC.Tc.Types.Constraint, Note [Insoluble Wanteds], especially (IW2)
There is a small change in the error message for T14172, but it looks
entirely acceptable to me.

ghc-internal: Fix incomplete matches on IOError
As noted in #25362, these incomplete matches were previously not being

`GHC.Internal.Event.Windows.withException`.

ci: Add support for ONLY_JOBS variable to trigger any validation pipeline
By setting the ONLY_JOBS variable to the name of the job (or multiple
jobs), the resulting
pipeline will include a validation job for that pipeline.
For example - if you set ONLY_JOBS="x86_64-linux-ubuntu22_04-validate"
then a ubuntu22_04 job will be included in the validation pipeline. This
is useful for testing specific jobs.
Fixes #25332
