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.

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.

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
