commit 9545e9f96beda6e9f2205bdb3c3e96edaf8d9e2b
Author: Andreas Arnez <arnez@linux.ibm.com>

Bug 400491 s390x: Sign-extend immediate operand of LOCHI and friends
The VEX implementation of each of the z/Architecture instructions LOCHI,
LOCHHI, and LOCGHI treats the immediate 16-bit operand as an unsigned
integer instead of a signed integer. This is fixed.
