If we cannot load a constant into a register in one insn, and that
constant is a valid mask (for rotate instructions), we currently
prefer to load -1 and then mask it.  This patch makes us not do that if
instead we could use two add or or instructions, since those are
sometimes faster on certain CPUs (and never are slower).


	* config/rs6000/rs6000.md (splitter to load of -1 and mask): Don't

Add an assert to leaf_function_p to ensure it is not called from a
prolog or epilog sequence (which would incorrectly return true in a
non-leaf function).  There are several targets which still call
leaf_function_p, and while most appear safe or appear aware of the
issue, it is likely not all such calls are safe.  This check enables
any such latent bugs to be found.
