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 interface6;

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

interface I
{
    void Ifunc();
}

interface J
{
    void Jfunc();
}

class C : I,J
{
    int i;
    int j;
    void Ifunc()
    {
        i++;
    }
    void Jfunc()
    {
        j++;
    }
}

void main()
{
    C c = new C;
    c.Ifunc();
    c.Jfunc();
    I i = c;
    i.Ifunc();
    J j = c;
    j.Jfunc();
    C c2 = cast(C)i;
    c2.Ifunc();
    c2.Jfunc();
    C c3 = cast(C)j;
    c3.Ifunc();
    c3.Jfunc();
    assert(c.i == 4);
    assert(c.j == 4);
}
