[JSC] Make PerfLog work on Darwin
https://bugs.webkit.org/show_bug.cgi?id=260626
rdar://problem/114345611

Reviewed by Justin Michaud.

This patch makes PerfLog work on Darwin, which generates JITDump[1] on Darwin.
While this is not performance efficient enough, we can later optimize the way to dump this, and try using it for a prototype.
