hadrian: fix ghc-pkg uses (#17601)

Make sure ghc-pkg doesn't read the compiler "settings" file by passing
--no-user-package-db.

Small optimization to CmmSink.

Inside `regsUsedIn` we can avoid some thunks by specializing the
recursion. In particular we avoid the thunk for `(f e z)` in the
MachOp/Load branches, where we know this will evaluate to z.

Reduces allocations for T3294 by ~1%.

Cleanup some primop constructor names

Harmonize the internal (big sum type) names of the native vs fixed-sized
number primops a bit. (Mainly by renaming the former.)

No user-facing names are changed.

withTimings: Emit allocations counter

This will allow us to back out the allocations per compiler pass from
the eventlog. Note that we dump the allocation counter rather than the
difference since this will allow us to determine how much work is done
*between* `withTiming` blocks.

ThreadPaused: Don't zero slop until free vars are pushed

When threadPaused blackholes a thunk it calls `OVERWRITING_CLOSURE` to
zero the slop for the benefit of the sanity checker. Previously this was
done *before* pushing the thunk's free variables to the update
remembered set. Consequently we would pull zero'd pointers to the update
remembered set.

nonmoving: Fix regression from TSAN work

The TSAN rework (specifically aad1f803) introduced a subtle regression
in GC.c, swapping `g0` in place of `gen`. Whoops!

Fixes #18997.

rts/Messages: Add missing write barrier in THROWTO message update

After a THROWTO message has been handle the message closure is
overwritten by a NULL message. We must ensure that the original
closure's pointers continue to be visible to the nonmoving GC.

Updates: Don't zero slop until closure has been pushed

Ensure that the the free variables have been pushed to the update
remembered set before we zero the slop.
