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.

class A {
    int i;
    int l;
    this(bool b,bool b2=false) {
        if (b) this = new B;
        i = 4;
        if (b2) this = new C;
        l = 64;
    }
}
class B : A{
    this() {
        super(false);
    }
}
class C : A{
    this() {
        super(false);
    }
}
void main() {
}
