finder: Add `IsBootInterface` to finder cache keys

Backport note: I have ported `uncacheModule` instead of removing it as
is done in 0d170eafacba55325dc00d0434d4462275d4376e since the necessary
type change is likely easier for possible GHC API users to accommodate
than outright removal.

driver: always merge objects when possible

This patch makes the driver always merge objects with `ld -r` when
possible, and only fall back to calling `ar -L` when merge objects
command is unavailable. This completely reverts !8887 and !12313,
given more fixes in Cabal seems to be needed to avoid breaking certain
configurations and the maintainence cost is exceeding the behefits in
this case :/

LLVM: use sse4.2 instead of sse42

LLVM expects the former instead of the latter since version 3.4.

Fixes #25019

LLVM: make SSE4.2 imply +popcnt

For consistency with the NCG as well as with Clang and GCC, we make
the SSE4.2 feature flag imply +popcnt when using the LLVM backend.

Fixes #25353

testsuite: use copy_files in T23405

This prevents the tree from being dirtied when the file is modified.

Consider Wanteds with rewriters as insoluble

This MR fixes #25325

See GHC.Tc.Types.Constraint, Note [Insoluble Wanteds], especially (IW2)

There is a small change in the error message for T14172, but it looks
entirely acceptable to me.

Compatibility with 9.8.1 as boot compiler

This fixes several compatability issues when using 9.8.1 as the boot
compiler.

* Some ghc-prim bounds need relaxing
* ghc is no longer wired in, so we have to remove the -this-unit-id ghc
  call.

Fixes #24605

Revert "NCG: Fix a bug in jump shortcutting."

This commit was wrong, as noted in the `master` revert cfeb70d3fed9c135295359296208bd800bab418f.
It appears to have ultimately been superceded by 0fe2b410ac0d8951f07ffcc9f3c6c97bc312df48
which is already present in `ghc-9.8`.

This reverts commit 44e119c9b7622f76b1b7e8d22548376b2591402d.
