much better swap logic to support reentrancy and fix assert failure
Commit c74340f9 added backreferences as well as the idea of a ->swap
regex pointer to keep track of the match offsets in case of backtracking.
The problem is that when Perl re-enters the regex engine to handle
utf8::SWASHNEW, the ->swap is not saved/restored/cleared so any capture
from the utf8 (Perl) code could inadvertently modify the regex match
data that caused the utf8 swash to get built.
This change should close out RT #60508
