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 interface3;

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

interface I
{
    void func();
}

class C : I
{
    int i = 42;
    override void func()
    {
        printf("hello %d from %p\n", i, this);
        i++;
    }
}

void main()
{
    auto c = new C;
    {c.func();}
    {
        I i = c;
        {i.func();}
    }
    {printf("final %d\n", c.i);}
    {assert(c.i == 44);}
}
