A drastically improved architecture for local floating in CorePrep
that decouples the decision of whether a float is going to be let- or case-bound
from how far it can float (out of strict contexts, out of lazy contexts, to
top-level).
There are a couple of new Notes describing the effort:
* `Note [Floating in CorePrep]` for the overview
* `Note [BindInfo and FloatInfo]` for the new classification of floats
* `Note [Floats and FloatDecision]` for how FloatInfo is used to inform
floating decisions
This is necessary ground work for proper treatment of Strict fields and
unlifted values at top-level.
Fixes #23442.

This completes a5227080b57cb51ac34d4c9de1accdf6360b818b, the
`ghc-usage.txt` and `ghci-usage.txt` file are also used by the `ghc`
library so need to make sure they are present in the libdir even if we
are not going to build `ghc-bin`.
This also fixes things for cross compilers because the stage2
cross-compiler requires the ghc-usage.txt file, but we are using
the stage2 lib folder but not building stage3:exe:ghc-bin so
ghc-usage.txt was not being generated.

In `GHC.Rename.Names.mkImportOccEnv`, we sometimes discard one import
item in favour of another, as explained in Note [Dealing with imports]
in `GHC.Rename.Names`. However, this can cause us to lose track of
important parent information.
Consider for example #24084:
module M1 where { class C a where { type T a } }
module M2 ( module M1 ) where { import M1 }
module M3 where { import M2 ( C, T ); instance C () where T () = () }
When processing the import list of `M3`, we start off (for reasons that
are not relevant right now) with two `Avail`s attached to `T`, namely
`C(C, T)` and `T(T)`. We combine them in the `combine` function of
`mkImportOccEnv`; as described in Note [Dealing with imports] we discard
`C(C, T)` in favour of `T(T)`. However, in doing so, we **must not**
discard the information want that `C` is the parent of `T`. Indeed,
losing track of this information can cause errors when importing,
as we could get an error of the form
‘T’ is not a (visible) associated type of class ‘C’
We fix this by combining the two GREs for `T` using `plusGRE`.
Fixes #24084

Fix this error by passing -DNOSMP to CC as well.

Fixes #24091
Progress on #23966
Issue #24091 reports that `@ProjectVersion@` is no longer being
substituted in the GHC user's guide. I assume this is a recent issue,
but I am not sure how it's worked since
c1a3ecde720b3bddc2c8616daaa06ee324e602ab; it looks like both Hadrian and
configure are trying to substitute the same `.in` file!
Now only Hadrian does. That is better anyways; already something that
issue #23966 requested.
It seems like we were missing some dependencies in Hadrian. (I really,
really hate that this is possible!) Hopefully it is fixed now.

We used to have MIN_UPD_SIZE macro that describes the minimum reserved
size for thunks, so that the thunk can be overwritten in place as
indirections or blackholes. However, this macro has not been actually
defined or used anywhere since a long time ago; StgThunkHeader already
reserves a padding word for this purpose. Hence this patch which drops
stale mentions of MIN_UPD_SIZE.

ghc-api tests for wasm32 are more likely to timeout due to the large
wasm module sizes, especially when testing with wasm native tail
calls, given wasmtime's handling of tail call opcodes are suboptimal
at the moment. It makes sense to increase timeout specifically for
these tests on wasm32. This doesn't affect other targets, and for
wasm32 we don't increase timeout for all tests, so not to risk letting
major performance regressions slip through the testsuite.

48e391952c17ff7eab10b0b1456e3f2a2af28a9b

The linker however, failed to mask the `SYM_TYPE_DUP_DISCARD` value.
Thus `== SYM_TYPE_CODE` comparisons easily failed. This lead to us
relocating DATA lookups (GOT) into E8 (call) and E9 (jump) instructions.

As observed in #22141, GHC was not doing its due diligence in catching code
that should require `DataKinds` in order to use. Most notably, it was allowing
the use of arbitrary data types in kind contexts without `DataKinds`, e.g.,
```hs
data Vector :: Nat -> Type -> Type where
```
This patch revamps how GHC tracks `DataKinds`. The full specification is
written out in the `DataKinds` section of the GHC User's Guide, and the
implementation thereof is described in `Note [Checking for DataKinds]` in
`GHC.Tc.Validity`. In brief:
* We catch _type_-level `DataKinds` violations in the renamer. See
`checkDataKinds` in `GHC.Rename.HsType` and `check_data_kinds` in
`GHC.Rename.Pat`.
* We catch _kind_-level `DataKinds` violations in the typechecker, as this
allows us to catch things that appear beneath type synonyms. (We do *not*
want to do this in type-level contexts, as it is perfectly fine for a type
synonym to mention something that requires DataKinds while still using the
type synonym in a module that doesn't enable DataKinds.) See `checkValidType`
in `GHC.Tc.Validity`.
* There is now a single `TcRnDataKindsError` that classifies all manner of
`DataKinds` violations, both in the renamer and the typechecker. The
`NoDataKindsDC` error has been removed, as it has been subsumed by
`TcRnDataKindsError`.
* I have added `CONSTRAINT` is `isKindTyCon`, which is what checks for illicit
uses of data types at the kind level without `DataKinds`. Previously,
`isKindTyCon` checked for `Constraint` but not `CONSTRAINT`. This is
inconsistent, given that both `Type` and `TYPE` were checked by `isKindTyCon`.
Moreover, it thwarted the implementation of the `DataKinds` check in
`checkValidType`, since we would expand `Constraint` (which was OK without
`DataKinds`) to `CONSTRAINT` (which was _not_ OK without `DataKinds`) and
reject it. Now both are allowed.
* I have added a flurry of additional test cases that test various corners of
`DataKinds` checking.
Fixes #22141.

This patch implements the T2T (term-to-type) transformation in
expressions. Given a function with a required type argument
vfun :: forall a -> ...
the user can now call it as
vfun (Maybe Int)
instead of
vfun (type (Maybe Int))
The Maybe Int argument is parsed and renamed as a term (HsExpr), but then
undergoes a conversion to a type (HsType).
See the new function expr_to_type in compiler/GHC/Tc/Gen/App.hs
and Note [RequiredTypeArguments and the T2T mapping]
