Scrub some partiality in `GHC.Cmm.Info.Build`: `doSRTs` takes a `[(CAFSet, CmmDecl)]` but truly wants a `[(CAFSet, CmmStatics)]`.

packaging: Fix upload_ghc_libs.py script

This change reflects the changes where .cabal files are now generated by
hadrian rather than ./configure.

Fixes #22518

configure: Drop uses of AC_PROG_CC_C99

As noted in #22566, this macro is deprecated as of autoconf-2.70
`AC_PROG_CC` now sets `ac_cv_prog_cc_c99` itself.

Closes #22566.

configure: Use AS_HELP_STRING instead of AC_HELP_STRING

The latter has been deprecated.

See #22566.

Fix tests

T13253 imports MonadTrans, which acquired a quantified constraint in transformers-0.6, thus increase in allocations

Metric Increase:

Abstract over the right free vars

Fix #22459, in two ways:

(1) Make the Specialiser not create a bogus specialisation if
    it is presented by strangely polymorphic dictionary.
    See Note [Weird special case in SpecDict] in
    GHC.Core.Opt.Specialise

(2) Be more careful in abstractFloats
    See Note [Which type variables to abstract over]
    in GHC.Core.Opt.Simplify.Utils.

So (2) stops creating the excessively polymorphic dictionary in
abstractFloats, while (1) stops crashing if some other pass should
nevertheless create a weirdly polymorphic dictionary.

Fix shadowing lacuna in OccurAnal

Issue #22623 demonstrated another lacuna in the implementation
of wrinkle (BS3) in Note [The binder-swap substitution] in
the occurrence analyser.

I was failing to add TyVar lambda binders using
addInScope/addOneInScope and that led to a totally bogus binder-swap
transformation.

Very easy to fix.

Fix an assertion check in addToEqualCtList

The old assertion saw that a constraint ct could rewrite itself
(of course it can) and complained (stupid).

Fixes #22645

Revert "rts: Drop racy assertion"

The logic here was inverted. Reverting the commit to avoid confusion
when examining the commit history.

This reverts commit b3eacd64fb36724ed6c5d2d24a81211a161abef1.

rts: Drop racy assertion

0e274c39bf836d5bb846f5fa08649c75f85326ac added an assertion in
`dirty_MUT_VAR` checking that the MUT_VAR being dirtied was clean.
However, this isn't necessarily the case since another thread may have
raced us to dirty the object.
