For unknown reasons, Java 1.5 on 64-bit HP-UX 11.11 does signed
computation of the new IAOQ value in the signal handler. In the
current code these bits are not masked when returning to narrow

This shouldn't be needed, because we are already masking these bits later, in
cpu_get_tb_cpu_state. But I do have some cleanups in this area, and perhaps one of them
matters.
