<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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%.

Harmonize the internal (big sum type) names of the native vs fixed-sized

No user-facing names are changed.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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.
