When allocating an anonymous IOSurface-backed GLImage, we have the
sequence of calls
- IOSurfaceCreate
- IOSurfaceCreateMachPort
- IOSurfaceRelease (implicitly in ScopedCFTypeRef<IOSurfaceRef>)
- IOSurfaceLookupFromMachPort
The final call persistently fails on some machines.

This adds a CHECK when that call fails, so we can assess how often
it occurs in the wild.

This also adds a call to IOSurfaceCreateMachPort and
IOSurfaceLookupFromMachPort before the implicit IOSurfaceRelease, to
see if this may be the result of a reference counting bug.

Add lots more LOG(ERROR) spew to help further diagnose this.
