Implemented proper support for naked asm using llvm module level asm. Still not 100% complete, but already 1000 times better that what we had before. Don's BignumX86 implementation from Tango (when turned into a standalone unittest) seems to fully work with no changes, and great performance :) Fixed align N; in asm blocks. Fixed inreg parameter passing on x86 for ref/out params. Removed support for lazy initialization of function local static variables, I have no idea why I ever implemented this, it's not in the D spec, and DMD doesn't support it :P Some of the global variable related changes might cause minor regressions, but they should be easily fixable.

interface MyInterface
{
    int func();
}

class MyClass : MyInterface
{
    int var;
    int func()
    {
        return var;
    }
}

void func1(MyInterface i)
{
    int delegate() dg = &i.func;
    func2(dg);
}

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

void func2(int delegate() dg)
{
    int i = dg();
    printf("%d\n", i);
}

void main()
{
    auto c = new MyClass;
    c.var = 42;
    func1(c);
}
