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 mini.nested13;

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

void main()
{
    int var = 2;

    void exec(void delegate() dg)
    {
        printf("var = %d\n", var);
        dg();
    }

    void foo()
    {
        printf("var = %d\n", var);
        assert(var == 5);
    }

    void bar()
    {
        printf("var = %d\n", var);
        var += 3;
        exec(&foo);
    }

    printf("var = %d\n", var);
    exec(&bar);

    return 0;
}
