Add test for #23540

`T23540.hs` makes use of `explainEv` from `HieQueries.hs`, so
`explainEv` has been moved to `TestUtils.hs`.

Make some evidence uses reachable by toHie

Resolves #23540, #23120

This adds spans to certain expressions in the typechecker and renamer,
and lets 'toHie' make use of those spans. Therefore the relevant
evidence uses for the following syntax will now show up under the
expected nodes in 'HieAst's:

- Overloaded literals ('IsString', 'Num', 'Fractional')

- Natural patterns and N+k patterns ('Eq', 'Ord', and instances from the
  overloaded literals being matched on)

- Arithmetic sequences ('Enum')

- Monadic bind statements ('Monad')

- Monadic body statements ('Monad', 'Alternative')

- ApplicativeDo ('Applicative', 'Functor')

- Overloaded lists ('IsList')

Also see Note [Source locations for implicit function calls]

In the process of handling overloaded lists I added an extra 'SrcSpan'
field to 'VAExpansion' - this allows us to more accurately reconstruct
the locations from the renamer in 'rebuildHsApps'. This also happens to
fix #23120.

See the additions to Note [Looking through HsExpanded]

Misc cleanup

- Builtin.PrimOps: ReturnsAlg was used only for unboxed tuples.
  Rename to ReturnsTuple.
- Builtin.Utils: use SDoc for a panic message.
  The comment about <<details unavailable>> was obsoleted by e8d356773b56.
- TagCheck: fix wrong logic. It was zipping a list 'args' with its
  version 'args_cmm' after filtering.
- Core.Type: remove an outdated 1999 comment about unlifted polymorphic types
- hadrian: remove leftover debugging print

Export setInertSet from GHC.Tc.Solver.Monad

We used to export getTcSInerts and setTcSInerts from GHC.Tc.Solver.Monad.
These got renamed to getInertSet/setInertSet in e1590ddc. That commit also removed
the export of setInertSet, but that function is useful for the GHC API.

Don't bundle children for non-parent Avails

We used to bundle all children of the parent Avail with things that
aren't the parent, e.g. with

  class C a where
    type T a
    meth :: ..

we would bundle the whole Avail (C, T, meth) with all of C, T and meth,
instead of only with C.

Avoiding this fixes #23570

Bump submodules of hpc and hpc-bin to version 0.7.0.0

hpc 0.7.0.0 dropped SafeHaskell safety guarantees in order to simplify
compatibility with newer versions of the directory package which
dropped all SafeHaskell guarantees.

Add a test for #21765

This issue (of reporting a constraint as being redundant even though
removing it causes typechecking to fail) was fixed in aed1974e.
This commit simply adds a regression test.

Fixes #21765

Export foldl' from Prelude and bump submodules

See https://github.com/haskell/core-libraries-committee/issues/167 for discussion

Metric Decrease:
    T8095
    T13386
Metric Increase:
    T13386
    T8095

T8095 ghc/alloc decreased on x86_64, but increased on aarch64.
T13386 ghc/alloc decreased on x86_64-windows, but increased on other platforms.
Neither has anything to do with `foldl'`, so I conclude that both are flaky.

Fix example in GHC user guide in SafeHaskell section

The example given in the SafeHaskell section uses an implementation of
Monad which no longer works. This MR removes the non-canonical return
instance and adds the necessary instances of Functor and Applicative.

rts: Fix invalid symbol type

I suspect this code is dead since we haven't observed this failing

rts/RtsSymbols: Add AArch64 outline atomic operations

Fixes #22012 by adding the symbols described in
https://github.com/llvm/llvm-project/blob/main/llvm/docs/Atomics.rst#libcalls-atomic.

Ultimately this would be better addressed by #22011, but this is a first
step in the right direction and fixes the immediate symptom.

Note that we dropped the `__arch64_cas16` operations as these provided
by all platforms's compilers. Also, we don't link directly against the
libgcc/compiler-rt definitions but rather provide our own wrappers to
work around broken toolchains (e.g. https://bugs.gentoo.org/868018).
