PR 1932/cpukit
* cpu_asm.S: At some point the interrupt trap handler causes a
window-overflow and the window overflow trap handler crashes when
writing to 0. I found that this is because the WIM was bad, to the
window overflow handler uses a uninitialized stack pointer in a
window never used.
* g3=CWP, not WIM
* CWP is incremented by done_flushing no need doing that here also
* I see no reason to create an additional stack frame (save)
* Must turn off traps when updating WIM (maybe already done by caller?)
