Bug 434296 - s390x: Rework IR conversion of VISTR

The z/Architecture instruction VISTR is currently transformed to a dirty
helper that executes the instruction.  This can cause false positives with
memcheck if the input string contains undefined characters after the
string terminator.  Implement without a dirty helper and emulate the
instruction instead.
