-----------
Every Timer objects wastes 7 bytes for padding
https://bugs.webkit.org/show_bug.cgi?id=268703
Reviewed by Darin Adler.
Use a CompactRefPtrTuple to avoid 7-byte padding at the end of each Timer
object.
Also use iso-heap for ThreadTimerHeapItem since this object historically had bad
memory management bugs.
