Preprocessed and reduced test-case

- Configure with --target=crisv32-axis-elf --enable-languages=c (the latter
optional.)
- Build with "make all-gcc"
- Run as gcc/cc1 -O2 -S g.i
- Observe:
/home/hp/g.i: In function '__muldi3':
/home/hp/g.i:22: internal compiler error: in process_bb_node_lives, at
ira-lives.c:677
NB: If you configure using --target=cris-axis-elf, you need to add -march=v32
to the cc1 options.
