Change the numbering of static ctors/dtors to be module based instead of being global. This fixes #210 by making sure that the static ctor always gets the same number, regardless of the order of the modules given at the command line.

extern(C) int printf(char*, ...);

static this()
{
    printf("static this\n");
}

static ~this()
{
    printf("static ~this\n");
}

void main()
{
    printf("main\n");
}
