rs6000: Make constant formation a tiny bit better

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).

Fix bogus pr78886.c failure for avr

The test fails for avr because malloc has been declared to take
an unsigned long, whereas size_t for avr is only unsigned int.

Fixed by typedef'ing __SIZE_TYPE__ to size_t and using it in the
malloc function declaration.
