Hi -

I've noticed that
  chpl --print-passes test/extern/ferguson/externblock/define.chpl
now core dumps in the compiler because
the extern block support tries to do
  module->initFn->insertAtHead(result);
when trying to add a global variable,
but module->initFn is NULL.

This used to work but I recall seeing some recent
changes to module initialization.

Since readExternC runs fairly early on
(so that it can happen before scopeResolve),
it sometimes changes the AST in odd ways.
How should it add a global variable?
(Is there a way to request that the module's
  init function be created, for example? Or
  should it be doing something else?)

Thanks,

-michael
