re PR target/89369 (pseudo-RNG miscompiled on s390x-linux with -O2 -march=zEC12 -mtune=z13 starting with r266203)
PR target/89369
* config/s390/s390.md (*r<noxa>sbg_<mode>_srl_bitmask,
*r<noxa>sbg_<mode>_sll, *r<noxa>sbg_<mode>_srl): Don't construct
pattern in a temporary buffer.
(*r<noxa>sbg_sidi_srl): Likewise. Always use 32 as I3 rather
than 64-operands[2].
* gcc.c-torture/execute/pr89369.c: New test.
* gcc.target/s390/md/rXsbg_mode_sXl.c (rosbg_si_srl,
rxsbg_si_srl): Expect last 3 operands 32,63,62 rather than
34,63,62.
