[JSC] Consolidate vm access in OMG into one value
https://bugs.webkit.org/show_bug.cgi?id=306413
rdar://169076114
Reviewed by Sosuke Suzuki.
VM* is used for mutatorFence and write-barrier in OMG.
But since it looks like just a load from instance, we end up loading it
each time. Let's define it m_vmValue just after obtaining instanceValue.
Since this is immutable load, if nobody is using it, it will be removed
in DCE phase.
