hadrian: fix ghc-pkg uses (#17601)

Make sure ghc-pkg doesn't read the compiler "settings" file by passing
--no-user-package-db.

gitlab-ci: Introduce a nightly cross-compilation job

This adds a job to test cross-compilation from x86-64 to AArch64 with
Hadrian.

Fixes #18234

Small optimization to CmmSink.

Inside `regsUsedIn` we can avoid some thunks by specializing the
recursion. In particular we avoid the thunk for `(f e z)` in the
MachOp/Load branches, where we know this will evaluate to z.

Reduces allocations for T3294 by ~1%.

Cleanup some primop constructor names

Harmonize the internal (big sum type) names of the native vs fixed-sized
number primops a bit. (Mainly by renaming the former.)

No user-facing names are changed.

Cleanup number primop conversion names

Don't use "extend" or "narrow" in some of the user-facing primops
names for conversions.

  - Names like `narrowInt32#` are misleading when `Int` is 32-bits.

  - Names like `extendInt64#` are flat-out wrong when `Int is
    32-bits.

  - `narrow{Int,Word}<N>#` however map a type to itself, and so don't
    suffer from this problem. They are left as-is.

Make proper fixed-with number literals

(Progress towards #11953, #17377, #17375)

Besides being nicer to use, this also will allow for better constant
folding for the fixed-width types, on par with what `Int#` and `Word#`
have today.

Make fixed-size `Int32#` and `Int64#`

The boxed Int64 uses Int64#, but Int32# still uses Int#. The 32-bit case
is less pressing to change because it is not a source of brittle
CPP---it is the same thing on all platforms.

We need Int64/Word64 constant folding to avoid the let/app restriction on Core, so
that is implemented now. 32-bit constant unfolding and 32-bit literals
are left as follow-up.

This is the bulk of #11953

Inline INT64 and WORD64 macros in primops.txt.pp

The definition is now unconditional so there is no reason for that CPP.

Copy enumFrom* implementations from Int/Word for Int64/Word64

Without this, we don't get proper list fusion.

I think this sort of copying is OK for now, but we absolutely need
something better if we are going to make `IntN` use `IntN#` for all `N`.
The degree to which proper metaprogramming has been punted upon by
factoring everything through the native-sized types is disconcerting.

`integerFromInt64#` can be inlined when the word size is >= 64 bits

Maybe this will help with the renaming test failure?
