Testsuite: more precise test options

Necessary for newer cross-compiling backends (JS, Wasm) that don't
support TH yet.

Use TcRnVDQInTermType in noNestedForallsContextsErr (#20115)

When faced with VDQ in the type of a term, GHC generates the following
error message:

	Illegal visible, dependent quantification in the type of a term
	(GHC does not yet support this)

Prior to this patch, there were two ways this message could have been
generated and represented:

	1. with the dedicated constructor TcRnVDQInTermType
	    (see check_type in GHC.Tc.Validity)
	2. with the transitional constructor TcRnUnknownMessage
	    (see noNestedForallsContextsErr in GHC.Rename.Utils)

Not only this led to duplication of code generating the final SDoc,
it also made it tricky to track the origin of the error message.

This patch fixes the problem by using TcRnVDQInTermType exclusively.

Remove source location information from interface files

This change aims to minimize source location information leaking
into interface files, which makes ABI hashes dependent on the
build location.

The `Binary (Located a)` instance has been removed completely.

It seems that the HIE interface still needs the ability to
serialize SrcSpans, but by wrapping the instances, it should
be a lot more difficult to inadvertently add source location
information.

Add missing dict binds to specialiser

I had forgotten to add the auxiliary dict bindings to the
/unfolding/ of a specialised function.  This caused #22358,
which reports failures when compiling Hackage packages
     fixed-vector
     indexed-traversable

Regression test T22357 is snarfed from indexed-traversable

Pass correct package db when testing stage1.

It used to pick the db for stage-2 which obviously didn't work.

Minor SDoc-related cleanup

* Rename pprCLabel to pprCLabelStyle, and use the name pprCLabel
  for a function using CStyle (analogous to pprAsmLabel)
* Move LabelStyle to the CLabel module, it no longer needs to be in Outputable.
* Move calls to 'text' right next to literals, to make sure the text/str
  rule is triggered.
* Remove FastString/String roundtrip in Tc.Deriv.Generate
* Introduce showSDocForUser', which abstracts over a pattern in
  GHCi.UI

rts: `name` argument of `createOSThread` can be `const`

Since we don't intend to ever change the incoming string, declare this
to be true.

Also, in the POSIX implementation, the argument is no longer `STG_UNUSED`
(since ee0deb8054da2a597fc5624469b4c44fd769ada2) in any code path.

rts: fix lifetime of `start_thread`s `name` value

Since, unlike the code in ee0deb8054da2^, usage of the `name` value
passed to `createOSThread` now outlives said function's lifetime, and
could hence be released by the caller by the time the new thread runs
`start_thread`, it needs to be copied.

rts: fix OS thread naming in ticker

Since ee0deb805, the use of `pthread_setname_np` on Darwin was fixed
when invoking `createOSThread`. However, the 'ticker' has some
thread-creation code which doesn't rely on `createOSThread`, yet also
uses `pthread_setname_np`.

This patch enforces all thread creation to go through a single
function, which uses the (correct) thread-naming code introduced in
ee0deb805.

ThToHs: fix overzealous parenthesization

Before this patch, when converting from TH.Exp to LHsExpr GhcPs,
the compiler inserted more parentheses than required:

	((f a) (b + c)) d

This was happening because the LHS of the function application was
parenthesized as if it was the RHS.

Now we use funPrec and appPrec appropriately and produce sensibly
parenthesized expressions:

	f a (b + c) d

I also took the opportunity to remove the special case for LamE,
which was not special at all and simply duplicated code.

Add accurate skolem info when quantifying

Ticket #22379 revealed that skolemiseQuantifiedTyVar was
dropping the passed-in skol_info on the floor when it encountered
a SkolemTv.  Bad!  Several TyCons thereby share a single SkolemInfo
on their binders, which lead to bogus error reports.

testsuite: Add tests for T22347

These are fixed in recent versions but might as well add regression
tests.
