[svn r89] Fixed a bunch of problems with template instance across multiple modules. Fixed initialization of function local static variables, with a non const initializer (now happens on first call using a global to make sure it only happens once.)

module bug2;
struct Vec { Vec barf() { return Vec(); } }
class test { this(Vec whee) { } }
void main() { Vec whee; new test(whee.barf()); }
