[JSC] Make DFG mayExit more precise
https://bugs.webkit.org/show_bug.cgi?id=257951
rdar://110628197
Reviewed by Justin Michaud.
Making this precise is particularly important for numerical compute-intensive
functions,
so that we can avoid unnecessary OSR exit-driven MovHint, which keeps some of
unnecessary
arithmetic ops alive.
