[Bug target/30485] New: ICE in rs6000_emit_vector_compare when building with -fno-trapping-math

[jconner at apple dot com]

The tests pr23816-1.c and vect-111.c (from gcc.dg/vect) generate an ICE when
compiled with -fno-trapping-math for rs6000:

$ gcc pr23816-1.c -fno-trapping-math -ftree-vectorize -maltivec -O2
pr23816-1.c: In function 'foo':
pr23816-1.c:9: internal compiler error: in rs6000_emit_vector_compare, at
config/rs6000/rs6000.c:11962
Please submit a full bug report,
with preprocessed source if appropriate.

$ gcc vect-111.c -fno-trapping-math -ftree-vectorize -maltivec -O2
vect-111.c: In function 'main1':
vect-111.c:19: internal compiler error: in rs6000_emit_vector_compare, at
config/rs6000/rs6000.c:11962

I have a patch for this that I'll submit...
