bump importance, since it's blocking Phobos PR#2266.

Hmm, actually, this bug appears to have been fixed on git HEAD. Could you try again please?

I take that back. This bug is still triggering when compiling with -O. I'm going to try to reduce it.

Minimal failing test case:
-----
// Compile with: dmd -O
bool prop(real x) { return false; }
double f(real) { return double.init; }
void main()
{
    real fc = f(real.init);
    if (fc == 0 || fc.prop) {}
}
-----

The ICE goes away if compiling without -O. Looks like an optimizer bug.
