[JSC] Share VM-independent JIT thunks
https://bugs.webkit.org/show_bug.cgi?id=320916
rdar://183943385
Reviewed by Yijia Huang.
We have various handler IC thunks and others, but most of them do not
need to have embedded VM*, which means they are VM-independent. Let's
share them globally among multiple VMs.
