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?

Fix Word64/Int64 constant-folding

I've refactored literal narrow/coerce functions to make them more
generic. Hence this patch incidentally implements basic support for
Int8/16/32 and Word8/16/32 in Core.
