Trigger GC when crossing warning threshold on iOS
https://bugs.webkit.org/show_bug.cgi?id=273830
rdar://127677553
Reviewed by Geoffrey Garen.
On iOS where we have fairly strict memory limits, sometimes the mutator can get
far ahead of the
GC. We might wait until a PROC_LIMIT_CRITICAL event fires before a full GC
occurs, at which point
the process is already eligible to be killed by the OS.
To try and reduce the number of foreground OOMs, let's also trigger a full GC
if it hasn't occurred
recently when a PROC_LIMIT_WARNING event fires (which is 80% of the critical
threshold).
