[ecj] Patch: FYI: another quick-stack-flushing patch

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the gcj-eclipse branch.

We should also flush the quick stack on a COMPONENT_REF, as one of
those may trap.

I'm not sure whether we need to strip off conversions here or
not... Andrew, do you know?
