  Log Message:
  -----------
  tcg: Add tcg_gen_gvec_dup_imm

Add a version of tcg_gen_dup_* that takes both immediate and
a vector element size operand.  This will replace the set of
tcg_gen_gvec_dup{8,16,32,64}i functions that encode the element
size within the function name.

  Log Message:
  -----------
  target/s390x: Use tcg_gen_gvec_dup_imm

The gen_gvec_dupi switch is unnecessary with the new function.
Replace it with a local gen_gvec_dup_imm that takes care of the
register to offset conversion and length arguments.

Drop zero_vec and use use gen_gvec_dup_imm with 0.

For the benefit of compatibility of function pointer types,
we have standardized on int32_t and int64_t as the integral
argument to tcg expanders.

We converted most of them in 474b2e8f0f7, but missed the rotates.
