<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Cleanup OVERWRITING_CLOSURE logic
The code is just more confusing than it needs to be. We don't need to mix
the threaded check with the ldv profiling check since ldv's init already
checks for this. Hence they can be two separate checks. Taking the sanity
checking into account is also cleaner via DebugFlags.sanity. No need for
checking the DEBUG define.
The ZERO_SLOP_FOR_LDV_PROF and ZERO_SLOP_FOR_SANITY_CHECK definitions the
old code had also make things a lot more opaque IMO so I removed those.

The new ASSERT in LDV_recordDead() was being tripped up by MVars when
removeFromMVarBlockedQueue() calls OVERWRITING_CLOSURE() via
OVERWRITE_INFO().

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Always zero shrunk mutable array slop when profiling
When shrinking arrays in the profiling way we currently don't always zero
the leftover slop. This means we can't traverse such closures in the heap
profiler. The old Note [zeroing slop] and #8402 have some rationale for why
this is so but I belive the reasoning doesn't apply to mutable
closures. There users already have to ensure multiple threads don't step on
each other's toes so zeroing should be safe.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">HsToCore: Eta expand left sections
Strangely, the comment next to this code already alluded to the fact
that even simply eta-expanding will sacrifice laziness. It's quite
unclear how we regressed so far.
See #18151.

this warning was emitted.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Modify file paths to module paths for new module hierarchy
This updates comments only.
This patch replaces module references according to new module
hierarchy [1][2].
For files under the `compiler/` directory, I replace them as
module paths instead of file paths. For instance,
`GHC.Unit.State` instead of `compiler/GHC/Unit/State.hs` [3].
For current and future haddock's markup, this patch encloses
the module name with "" [4].
