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.

static foocalled = false;
static barcalled = false;
void foo() { foocalled = true; }
void bar() { barcalled = true; }

void f(bool b)
{
  return b ? foo() : bar();
}

void main()
{
  f(true);
  assert(foocalled && !barcalled);
  f(false);
  assert(foocalled && barcalled);
}
