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 Iin
{
    void[] read(size_t n);
}

interface Iout
{
    size_t write(void[] d);
}

class C : Iin
{
    void[] read(size_t n)
    {
        return null;
    }

    size_t write(void[] d)
    {
        return 0;
    }
}

void main()
{
    scope c = new C;
}
