WebKitPerformanceSignpostEnabled envvar is on
https://bugs.webkit.org/show_bug.cgi?id=297938
rdar://159232739
Reviewed by Yijia Huang.
This patch adds JSC::ProfilerSupport hook into performance.measure
when WebKitPerformanceSignpostEnabled envvar is on.
This will also emit some additional information (when text-marker is
enabled) for performance analysis via JSC::ProfilerSupport as the same
to JSGlobalObject's signposts.
