<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix some missed opportunities for preInlineUnconditionally
There are two signficant changes here:
* Ticket #18815 showed that we were missing some opportunities for
preInlineUnconditionally. The one-line fix is in the code for
GHC.Core.Opt.Simplify.Utils.preInlineUnconditionally, which now
switches off only for INLINE pragmas. I expanded
Note [Stable unfoldings and preInlineUnconditionally] to explain.
* When doing this I discovered a way in which preInlineUnconditionally
was occasionally /too/ eager. It's all explained in
Note [Occurrences in stable unfoldings] in GHC.Core.Opt.OccurAnal,
and the one-line change adding markAllMany to occAnalUnfolding.
I also got confused about what NoUserInline meant, so I've renamed
it to NoUserInlinePrag, and changed its pretty-printing slightly.
That led to soem error messate wibbling, and touches quite a few
files, but there is no change in functionality.
I did a nofib run. As expected, no significant changes.

I'm allowing a max-residency increase for T10370, which seems
very irreproducible. (See comments on !4241.) There is always
sampling error for max-residency measurements; and in any case
the change shows up on some platforms but not others.
