s390x/tcg: Implement VECTOR STRING RANGE COMPARE
Unfortunately, there is no easy way to avoid looping over all elements
in v2. Provide specialized variants for !cc,!rt/!cc,rt/cc,!rt/cc,rt and
all element types. Especially for different values of rt, the compiler
might be able to optimize the code a lot.
Add s390_vec_write_element().
