  Branch: 7.9

Compiler: Fixed over optimization in __INIT().

Constant expressions that have external dependencies that
evaluate to zero should not be removed, since they may
get overloaded later.

Also fixes forward refering constants like in the Calendar module:

program Foo = cFoo;
class cFoo {
// ...
}

Fixes [LysLysKOM 20361227]/Pike mailinglist 13656.

Thanks to Chris Angelico <rosuav@gmail.com> for the report.
