[JSC] Allow GC while running Baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=272561
rdar://126305877
Reviewed by Justin Michaud.
Baseline JIT is unlinked. So this should run without interfering with GC.
In this patch, we allow running GC while running Baseline JIT since some of
Baseline JIT (for mega functions) is really time-consuming.
This patch makes BaselineJITPlan always keep CodeBlock alive by using custom
isKnownToBeLiveAfterGC and isKnownToBeLiveDuringGC.
As a result, we can just run Baseline JIT without considering much.
