Since this variable will only affect d8, it doesn't need to be in common.gypi,
but can go into d8.gyp instead. In there, the only thing it should do is control
d8's dependency on the to-be-created v8vtune gyp target.

These definitions should then go into the to-be-created v8vtune target into a
direct_dependent_settings section (so they'll automatically affect targets
depending on v8vtune).
