There's a fairly simple bug - CollectVariables marks variables active just based on an invariant declaration, even if it shouldn't. Fix under way.

Invariant declaration doesn't make a variable active

Invariant declarations didn't affect static use before, but now they
are also skipped in CollectVariables so an invariant declaration is
not enough in itself to mark a variable as active. This fixes an
assert in CollectVariables.
