Andreas Arnez ddfc274b24 s390x: More fixes for z13 support
This patch addresses the following:

* Fix the implementation of LOCGHI.  Previously Valgrind performed 32-bit
  sign extension instead of 64-bit sign extension on the immediate value.

* Advertise VXRS in HWCAP.  If no VXRS are advertised, but the program
  uses vector registers, this could cause problems with a glibc built with
  "-march=z13".
