<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Post ticky entry counts to the eventlog
We currently only post the entry counters, not the other global
counters as in my experience the former are more useful. We use the heap
profiler's census period to decide when to dump.
Also spruces up the documentation surrounding ticky-ticky a bit.

This changes the "ticky" modifier to enable dumping of final STG as this
is generally needed to make sense of the ticky profiles.

<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.
