See also PR 17626. This is another bug in the peephole2 patterns; constants
aren't truncated/sign-extended when changing to a shorter mode. This causes
ICEs like the following:
x/gcc/testsuite/gcc.dg/cris-peep2-xsrand2.c: In function 'andwlsr':
x/gcc/testsuite/gcc.dg/cris-peep2-xsrand2.c:16: error: unrecognizable insn:
(insn 31 30 25 0 (set (reg:HI 10 r10)
(and:HI (reg:HI 10 r10)
(const_int 65399 [0xff77]))) -1 (nil)
(nil))
