Currently `ghc -M` fails to account for `.hs-boot` files correctly,
leading to issues with cross-package one-shot builds failing. This
currently manifests in `GHC.Exception` due to the boot file for
`GHC.Internal.Stack`. Work around this by adding an explicit `import`,
ensuring that `GHC.Internal.Stack` is built before `GHC.Exception`.

See #24436.

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.

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

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.

In nonmovingTidyWeaks we want to check if the key of a weak pointer
lives in the non-moving heap. We do this by checking the flags of the
block the key lives in. But we need to be careful with values that live
outside the Haskell heap, since they will lack a block descriptor and
looking for one may lead to a segfault. In this case we should just
accept that it isn't on the non-moving heap.

Non-moving segments are 8 blocks long and need to be aligned.
Previously we serviced allocations by grabbing 15 blocks, finding
an aligned 8 block group in it and returning the rest.
This proved to lead to high levels of fragmentation as a de-allocating a segment
caused an 8 block gap to form, and this could not be reused for allocation.

This patch introduces a segment allocator based around using entire
megablocks to service segment allocations in bulk.

When there are no free segments, we grab an entire megablock and fill it
with aligned segments. As the megablock is free, we can easily guarantee
alignment. Any unused segments are placed on a free list.

It only makes sense to free segments in bulk when all of the segments in
a megablock are freeable. After sweeping, we grab the free list, sort it,
and find all groups of segments where they cover the megablock and free
them.
This introduces a period of time when free segments are not available to
the mutator, but the risk that this would lead to excessive allocation
is low. Right after sweep, we should have an abundance of partially full
segments, and this pruning step is relatively quick.
