hadrian/hie-bios: pass -j to hadrian

This commit passes -j to hadrian in the hadrian/hie-bios scripts. When
the user starts HLS in a fresh clone that has just been configured, it
takes quite a while for hie-bios to pick up the ghc flags and start
actual indexing, due to the fact that the hadrian build step defaulted
to -j1, so -j speeds things up and improve HLS user experience in GHC.
Also add -j flag to .ghcid to speed up ghcid, and sets the Windows
build root to .hie-bios which also works and unifies with other
platforms, the previous build root _hie-bios was missing from
.gitignore anyway.

ci: enable parallelism in hadrian/ghci scripts

This commit enables parallelism when the hadrian/ghci scripts are
called in CI. The time bottleneck is in the hadrian build step, but
previously the build step wasn't parallelized.

m4: Correctly detect GCC version

When calling as `cc`, GCC does not outputs lowercased "gcc" at least in 13.2.1 version here.

```
$ cc --version
cc (GCC) 13.2.1 20230801
...
```

This fails the check and outputs the confusing message: `configure: $CC is not gcc; assuming it's a reasonably new C compiler`

This patch makes it check for upper-cased "GCC" too so that it works correctly:

```
checking version of gcc... 13.2.1
```

Move ClosureType type to ghc-internal

- Use ClosureType for InfoProv.ipDesc.
- Use ClosureType for CloneStack.closureType.
- Now ghc-heap re-exports this type from ghc-internal.

See the accompanying CLC proposal: https://github.com/haskell/core-libraries-committee/issues/210

Resolves #22600

StgToJS: Simplify ExprInline constructor of ExprResult

Its payload was used only for a small optimization in genAlts,
avoiding a few assignments for programs of this form:

  case NormalDataCon arg1 arg2 of x { NormalDataCon x1 x2 -> ... ; }

But when compiling with optimizations, this sort of code is
generally eliminated by case-of-known-constructor in Core-to-Core.
So it doesn't seem worth tracking and cleaning up again in StgToJS.

utils: remove unused lndir from tree

Ever since the removal of the make build system, the in tree lndir
hasn't been actually built, so this patch removes it.

add -fprof-late-overloaded and -fprof-late-overloaded-calls

* Refactor late cost centre insertion for extensibility
* Add two more late cost centre insertion methods that add SCCs to overloaded
  top level bindings and call sites with dictionary arguments.
* Some tests for the basic functionality of the new insertion methods
