compiler: Fingerprint more code generation flags

Previously our recompilation check was quite inconsistent in its
coverage of non-optimisation code generation flags. Specifically, we
failed to account for most flags that would affect the behavior of
generated code in ways that might affect the result of a program's
execution (e.g. `-feager-blackholing`, `-fstrict-dicts`)

Closes #23369.

compiler: Record original thunk info tables on stack

Here we introduce a new code generation option, `-forig-thunk-info`,
which ensures that an `stg_orig_thunk_info` frame is pushed before every
update frame. This can be invaluable when debugging thunk cycles and
similar.

See Note [Original thunk info table frames] for details.

Closes #23255.

Valid hole fits: don't panic on a Given

The function GHC.Tc.Errors.validHoleFits would end up panicking when
encountering a Given constraint. To fix this, it suffices to filter out
the Givens before continuing.

Fixes #22684

Use deb10 for i386 bindists

deb9 is now EOL so it's time to upgrade the i386 bindist to use deb10

Fix #23567, a specializer bug

Found by Simon in https://gitlab.haskell.org/ghc/ghc/-/issues/23567#note_507834

The testcase isn't ideal because it doesn't detect the bug in master,
unless doNotUnbox is removed as in
https://gitlab.haskell.org/ghc/ghc/-/issues/23567#note_507692.
But I have confirmed that with that modification, it fails before
and passes afterwards.

Fix deprecation of record fields

Commit 3f374399 inadvertently broke the deprecation/warning mechanism
for record fields due to its introduction of record field namespaces.

This patch ensures that, when a top-level deprecation is applied to
an identifier, it applies to all the record fields as well.
This is achieved by refactoring GHC.Rename.Env.lookupLocalTcNames, and
GHC.Rename.Env.lookupBindGroupOcc, to not look up a fixed number of
NameSpaces but to look up all NameSpaces and filter out the irrelevant
ones.

Introduce greInfo, greParent

These are simple helper functions that wrap the internal
field names gre_info, gre_par.

Refactor lookupGRE_... functions

This commit consolidates all the logic for looking up something in
the Global Reader Environment into the single function lookupGRE.
This allows us to declaratively specify all the different modes of
looking up in the GlobalRdrEnv, and avoids manually passing around
filtering functions as was the case in e.g. the function
GHC.Rename.Env.lookupSubBndrOcc_helper.

configure: Drop DllWrap command

We used to configure into settings a DllWrap command for windows
builds and distributions, however, we no longer do, and dllwrap is
effectively unused.

This simplification is motivated in part by the larger
toolchain-selection project (#19877, !9263)

Revert "CI: add JS release and debug builds, regen CI jobs"

This reverts commit 59c5fe1d4b624423b1c37891710f2757bb58d6af.

This commit added two duplicate jobs on all validate pipelines, so we
are reverting for now whilst we work out what the best way forward is.

Configure: canonicalise PythonCmd on Windows

This change makes PythonCmd resolve to a canonical absolute path on
Windows, which prevents HLS getting confused (now that we have a
build-time dependency on python).
