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 nested10;

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

void main()
{
    int j = 3;
    void F()
    {
        int i = j;
        printf("F: i = %d, j = %d\n", i, j);
        void G()
        {
            printf("G: i = %d, j = %d\n", i, j);
            j += i;
        }
        G();
    }
    F();
    printf("6 = %d\n", j);
    assert(j == 6);
}
