<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Zero out pinned block alignment slop when profiling

The heap profiler currently cannot traverse pinned blocks because of

alignment slop. This used to just be a minor annoyance as the whole block

is accounted into a special cost center rather than the respective object's

CCS, cf. #7275. However for the new root profiler we would like to be able

to visit _every_ closure on the heap. We need to do this so we can get rid

of the current 'flip' bit hack in the heap traversal code.

Since info pointers are always non-zero we can in principle skip all the

slop in the profiler if we can rely on it being zeroed. This assumption

caused problems in the past though, commit a586b33f8e ("rts: Correct

handling of LARGE ARR_WORDS in LDV profiler"), part of !1118, tried to use

the same trick for BF_LARGE objects but neglected to take into account that

shrink*Array# functions don't ensure that slop is zeroed when not

compiling with profiling.

Later, commit 0c114c6599 ("Handle large ARR_WORDS in heap census (fix

as we will only be assuming slop is zeroed when profiling is on.

This commit also reduces the ammount of slop we introduce in the first

place by calculating the needed alignment before doing the allocation for

small objects where we know the next available address. For large objects

we don't know how much alignment we'll have to do yet since those details

are hidden behind the allocateMightFail function so there we continue to

allocate the maximum additional words we'll need to do the alignment.

So we don't have to duplicate all this logic in the cmm code we pull it

into the RTS allocatePinned function instead.
