target-ppc: gen_pause for instructions: yield, mdoio, mdoom, miso
Call gen_pause for all "or rx,rx,rx" encodings other nop. This
provides a reasonable implementation for yield, and a better
approximation for mdoio, mdoom, and miso. The choice to pause for all
encodings !=0 leverages the PowerISA admonition that the reserved
encodings might change program priority, providing a slight "future
proofing".
