Bug 417281 - s390x: Fix register usage of conditional moves

The s390x register usage callback marks the target register of a
conditional move as HRmWrite only.  It fails to mention the fact that the
target register is also an input to the insn (unless the condition is
"never" or "always").

This was discovered while investigating "grail" failures on s390x and
fixes the majority of them.
