s390: Implement extzv for z10
* config/s390/predicates.md (nonzero_shift_count_operand): New.
* config/s390/s390-protos.h (s390_extzv_shift_ok): Declare.
* config/s390/s390.c (s390_extzv_shift_ok): New function.
* config/s390/s390.md (extzv): New expander.
(*extzv<GPR>_zEC12, *extzv<GPR>_z10): New insns.
(*pre_z10_extzv<GPR>): Rename from *extzv<GPR>; simplify with
