Fix bogus builtin-snprintf-warn-3.c failure for avr

The test declares a struct with an array member that has INT_MAX/32767
elements. This causes a "type xxx is too large" error for targets like
the avr, which has 16 bit pointers.

Fix by marking the test as unsupported for targets with ptr size < 32.

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).

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