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.

struct S {
    int a; int b; int c; int d = 7;
}
void test(int i) {
    S s = { 1, i };   // q.a = 1, q.b = i, q.c = 0, q.d = 7
    assert(s.a == 1);
    assert(s.b == i);
    assert(s.c == 0); // line 8
    assert(s.d == 7);
}
void main() {
    test(42);
}
