Why is this needed here when it wasn't before? Has some VM include been removed
from vm/globals.h?

[Søren Gjesse, 2012/01/16 12:55:30]

This was due to the wrong ordering of headers in isolate.cc. isolate.h was then
included after bigint_store.h causing Isolate to not be defined. The include
order in isolate.cc is fixed, but I have kept this new include here as this .h
file uses Isolate.
