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 nested7;
extern(C) int printf(char*, ...);

void main()
{
    int i;
    i = 52;
    printf("i = %d\n", i);

    void func()
    {
        i++;

        void func2()
        {
            i++;

            void func3()
            {
                i++;
            }

            func3();
        }

        func2();
    }

    func();

    printf("i = %d\n", i);
    assert(i == 55);
}
