s390/percpu: Implement this_cpu_try_cmpxchg()
Provide an s390 specific implementation of this_cpu_try_cmpxchg() for
the four and eight byte cases, if the compiler supports flag output
operands.
This variant uses the condition code set by cs/csg, which avoids a
compare instruction required by the generic variant and generates
slightly better code.
