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 interface2;

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

interface A
{
    void a();
}

interface B
{
    void b();
}

class C : A,B
{
    int i = 0;
    override void a()
    {
        printf("hello from C.a\n");
    }
    override void b()
    {
        printf("hello from C.b\n");
    }
}

void main()
{
    scope c = new C;
    {c.a();
    c.b();}
    {A a = c;
    a.a();}
    {B b = c;
    b.b();}
}
