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.

void main()
{
    auto a = new float[1024];
    auto b = new float[1024];
    auto c = new float[1024];

    for (auto i=0; i<1024; i++)
    {
        a[i] = i;
        b[i] = i*2;
        c[i] = i*4;
    }

    a[] = b[] + c[] / 2;

    foreach(i,v; a)
    {
        assert(eq(v, b[i] + c[i] / 2));
    }
}

float abs(float x)
{
    return x<0?-x:x;
}
bool eq(float a, float b)
{
    return abs(a-b) <= float.epsilon;
}
