-----------
[JSC] ICStats should report the actual set of handlers executed
https://bugs.webkit.org/show_bug.cgi?id=309935
rdar://172526524
Reviewed by Justin Michaud.
Adds tracking of the IC handler chains as they execute. This is done by
recording a given IC's total length when entering the chain then each
handler as it runs. When the next IC starts the previous chain gets
flushed.
No new tests, logging code, disabled by default.
