hadrian: Ensure that way-flags are passed to CC

Previously the way-specific compilation flags (e.g. `-DDEBUG`,
`-DTHREADED_RTS`) would not be passed to the CC invocations. This meant
that C dependency files would not correctly reflect
dependencies predicated on the way, resulting in the rather
painful #23554.

Closes #23554.

Native 32-bit Enum Int64/Word64 instances

This commits adds more performant Enum Int64 and Enum Word64 instances
for 32-bit platforms, replacing the Integer-based implementation.

These instances are a copy of the Enum Int and Enum Word instances with
minimal changes to manipulate Int64 and Word64 instead.

On i386 this yields a 1.5x performance increase and for the JavaScript
back end it even yields a 5.6x speedup.

Metric Decrease:
    T18964

ci: Pass -Werror when building hadrian in hadrian-ghc-in-ghci job

Warnings when building Hadrian can end up cluttering the output of HLS,
and we've had bug reports in the past about these warnings when building
Hadrian. It would be nice to turn on -Werror on at least one build of
Hadrian in CI to avoid a patch introducing warnings when building
Hadrian.

Fixes #23638

Desugar non-recursive lets to non-recursive lets (take 2)

This reverts commit 522bd584f71ddeda21efdf0917606ce3d81ec6cc. And
takes care of the case that I missed in my previous attempt. Namely
the case of an AbsBinds with no type variables and no dictionary
variable.

Ironically, the comment explaining why non-recursive lets were
desugared to recursive lets were pointing specifically at this case
as the reason. I just failed to understand that it was until Simon PJ
pointed it out to me.

See #23550 for more discussion.
