<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">nonmoving: Clear bitmap after initializing block size
Previously nonmovingInitSegment would clear the bitmap before
initializing the segment's block size. This is broken since
nonmovingClearBitmap looks at the segment's block size to determine how
much bitmap to clear.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">nonmoving: Explicitly memoize block count
A profile cast doubt on whether the compiler hoisted the bound out the
loop as I would have expected here. It turns out it did but nevertheless
it seems clearer to just do this manually.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Remove OneShotInfo field of LFReEntrant, document OneShotInfo
The field is only used in withNewTickyCounterFun and it's easier to
directly pass a parameter for one-shot info to withNewTickyCounterFun
instead of passing it via LFReEntrant. This also makes !2842 simpler.
Other changes:
- New Note (by SPJ) [OneShotInfo overview] added.
- Arity argument of thunkCode removed as it's always 0.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Refactor PprDebug handling
If `-dppr-debug` is set, then PprUser and PprDump styles are silently
replaced with PprDebug style. This was done in `mkUserStyle` and
`mkDumpStyle` smart constructors. As a consequence they needed a
DynFlags parameter.
Now we keep the original PprUser and PprDump styles until they are used
to create an `SDocContext`. I.e. the substitution is only performed in
`initSDocContext`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fully remove PprDebug
PprDebug was a pain to deal with consistently as it is implied by
`-dppr-debug` but it isn't really a PprStyle. We remove it completely
and query the appropriate SDoc flag instead (`sdocPprDebug`) via
helpers (`getPprDebug` and its friends).

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Pick up `EvVar`s bound in `HsWrapper`s for long-distance info
`HsWrapper`s introduce evidence bindings through `WpEvLam` which the
pattern-match coverage checker should be made aware of.
Failing to do so caused #18049, where the resulting impreciseness of
imcompleteness warnings seemingly contradicted with
`-Winaccessible-code`.
The solution is simple: Collect all the evidence binders of an
`HsWrapper` and add it to the ambient `Deltas` before desugaring
the wrapped expression.
But that means we pick up many more evidence bindings, even when they
wrap around code without a single pattern match to check! That regressed
`T3064` by over 300%, so now we are adding long-distance info lazily
through judicious use of `unsafeInterleaveIO`.
Fixes #18049.
