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.norun_debug10;

struct Vec2
{
    float x,y;
}

void main()
{
    Vec2 v2;
    char[] str = "hello";
    int i = void;
    float f = 3.14;
    func(v2, v2, str, i, f);
}

void func(Vec2 v2, ref Vec2 rv2, char[] str, out int i, ref float f)
{
    int* fail;
    *fail = 0;
}
