rts/win32: Ensure reliability of IO manager shutdown

When the Win32 threaded IO manager shuts down, `ioManagerDie` sends an
`IO_MANAGER_DIE` event to the IO manager thread using the
`io_manager_event` event object. Finally, it will closes the event object,
and invalidate `io_manager_event`.

Previously, `readIOManagerEvent` would see that `io_manager_event` is
invalid and return `0`, suggesting that everything is right with the
world. This meant that if `ioManagerDie` invalidated the handle before
the event manager was blocked on the event we would end up in a
situation where the event manager would never realize it was asked to
shut down.

Fix this by ensuring that `readIOManagerEvent` instead returns
`IO_MANAGER_DIE` when we detect that the event object has been
invalidated by `ioManagerDie`.

Fixes #23691.

Look through TH splices in splitHsApps

This modifies `splitHsApps` (a key function used in typechecking function
applications) to look through untyped TH splices and quasiquotes. Not doing so
was the cause of #21077. This builds on !7821 by making `splitHsApps` match on
`HsUntypedSpliceTop`, which contains the `ThModFinalizers` that must be run as
part of invoking the TH splice. See the new `Note [Looking through Template
Haskell splices in splitHsApps]` in `GHC.Tc.Gen.Head`.

Along the way, I needed to make the type of `splitHsApps.set` slightly more
general to accommodate the fact that the location attached to a quasiquote is
a `SrcAnn NoEpAnns` rather than a `SrcSpanAnnA`.

Fixes #21077.

linker/PEi386: Don't sign-extend symbol section number

Previously we incorrectly interpreted PE section numbers as signed
values. However, this isn't the case; rather, it's an unsigned 16-bit number
with a few special bit-patterns (0xffff and 0xfffe). This resulted in #22941
as the linker would conclude that the sections were invalid.

Fixing this required quite a bit of refactoring.

Closes #22941.

nativeGen/AArch64: Fix sign extension in MulMayOflo

Previously the 32-bit implementations of MulMayOflo would use the
a non-sensical sign-extension mode. Rewrite these to reflect what gcc 11
produces. Also similarly rework the 16- and 8-bit cases.

This now passes the MulMayOflo tests in ghc/test-primops> in all four
widths, including the precision tests.

Fixes #23721.

Fix (~) and (@) infix operators in TH splices (#23748)

8168b42a "Whitespace-sensitive bang patterns" allows GHC to accept
the following infix operators:

	a ~ b = ()
	a @ b = ()

But not if TH is used to generate those declarations:

	$([d| a ~ b = ()
	      a @ b = ()
	    |])

	-- Test.hs:5:2: error: [GHC-55017]
	--    Illegal variable name: ‘~’
	--    When splicing a TH declaration: (~_0) a_1 b_2 = GHC.Tuple.Prim.()

This is easily fixed by modifying `reservedOps` in GHC.Utils.Lexeme

[#23663] Show Flag Suggestions in GHCi

Makes suggestions when using `:set` in GHCi with a misspelled flag. This
mirrors how invalid flags are handled when passed to GHC directly. Logic
for producing flag suggestions was moved to GHC.Driver.Sesssion so it
can be shared.

resolves #23663

EPA make getLocA a synonym for getHasLoc

This is basically a no-op change, but allows us to make future changes
that can rely on the HasLoc instances

And I presume this means we can use more precise functions based on
class resolution, so the Windows CI build reports

Metric Decrease:
    T12234
    T13035
