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.

There are two parts to this commit. We moved the definition of BooleanFormula
over to L.H.S.BooleanFormula, and we parameterized it over the ghcPass instead
of over some arbitrary type.
That said the changes are largely superficial. Most effort was in dealing
with IFaceBooleanFormula, as we used to map the booleanformula to contain a
IfLclName and then transform it to to the IFaceBooleanFormula, but that's
no longer posssible in the current setup. Instead we just folded the
transformation from a Name to an IfLclName in the transformation
from BooleanFormula to IfaceBooleanFormula.
