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

ghc-bignum: add support for Word64#/Int64# on 64-bit arch

Fix fingerprint Core generation

Fix some tests

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?
