Avoid inlining the {SmallVector::Grow} function, as it is rarely used.
This reduces binary size, since {emplace_back} is called a lot, and
often {emplace_back} itself is inlined.
As another minor tweak the {Grow} function now returns the new end of
the used storage, to reduce binary size in {emplace_back} even more.
Also, there is a separate version without argument.

Since https://codereview.chromium.org/2777583003, the Boyer-Moore
lookahead (used by the irregexp engine) also looks inside submatches
to narrow down its range of accepted characters at specific offsets.
But the end of a submatch, designated by a PositiveSubmatchSuccess
action node, was not handled correctly. When a submatch terminates,
we have no knowledge of what may follow, and thus must accept any
character at following positions. This is done by the SetRest call
added in this CL.
An example, since this is fairly obscure:
/^.*?Y(((?=B?).)*)Y$/s
The initial non-greedy loop, together with the s flag,
will trigger an attempted Boyer-Moore lookahead. After this follows
an unconditional Y, a *-quantified loop matching any char and
containing a lookahead that matches either 1 B or 0 B's, and an
unconditional trailing Y.
When the BM lookahead scans the subject string for the beginning of
this pattern after the non-greedy loop, it should look for: a Y at
offset 0, and either a B, a Y, or '.' (-> any character) at offset 1.
Prior to this CL this was not the case:
- The lookaround is internally generated as a submatch.
- The optional 'B?' is unrolled into 'either B followed by submatch
end' or 'submatch end'.
- Filling in BM infos terminates when encountering a submatch end.
Thus in the former case we added B to the set of accepted characters
and terminated, while in the latter case we simply terminated.o
This CL ensures that BM will accept any character at any offset at or
exceeding the first encountered submatch end.

The previous fix for this bug (crrev.com/c/1678365) pessimistically
would mark all shadowed variables as maybe_assigned. Unfortunately,
this doesn't work across a parse/preparse boundary, where the shadowing
variable is found via Scope::AnalyzePartially while the shadowed
variable is outside of the preparser entry point. In those cases, the
referencing proxy is copied to the outer scope, in which case the
dynamicness of the original lookup is lost and the maybe_assigned
pessimisation no longer applies.
This means that maybe_assigned status of a variable is dependent on
which function is being parsed. In particular, it can cause bytecode
to change on recompilation, causing issues for lazy source positions.
This patch allows SetMaybeAssigned to walk its shadowed variables,
and recursively set them to maybe_assigned too. Checking for
maybe_assigned changing prevents this recursion from having a
quadratic performance failure mode.

This is a reland of fb4d54802e
Few test-serialize tests were not clearing the shared heap before using a
new snapshot, breaking the noembed build. This is fixed now and a check
has been added
(https://chromium-review.googlesource.com/c/v8/v8/+/1667415) to make
sure it doesn't happen again.
