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.

module interface5;

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

interface I
{
    void func();
}

class C : I
{
    int i;
    void func()
    {
        printf("C\n");
        i++;
    }
}

void main()
{
    C c = new C;
    c.func();
    {
        I i = c;
        c.func();

        C c2 = cast(C)i;
        c2.func();

        c.func();
        assert(c.i == 4);
    }
}
