[JSC] Fold microtask queueing slow path condition to m_canFastQueueMicrotask
https://bugs.webkit.org/show_bug.cgi?id=315743
rdar://178130672
Reviewed by Mark Lam and Yijia Huang.
Microtask queueing is extremely hot and any random additional load matters.
We add m_canFastQueueMicrotask flag which combines all of slow path
conditions into one, to avoid spreading slow path code from the fast path.
