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 nested8;
extern(C) int printf(char*, ...);

void main()
{
    int i = 1;
    void func()
    {
        printf("func()\n");
        i++;
        void func2()
        {
            printf(" func2()\n");
            int j = i + 1;
            void func3()
            {
                printf("  func3()\n");
                j++;
                printf("  done = %d\n", j);
            }
            func3();
            i = j;
            printf(" done = %d\n", j);
        }
        func2();
        printf("done\n");
    }
    func();
    printf("i == %d\n", i);
    assert(i == 4);
}
