target/s390x: Define TARGET_HAS_PRECISE_SMC
PoP (Sequence of Storage References -> Instruction Fetching) says: ... if a store that is conceptually earlier is made by the same CPU using the same effective address as that by which the instruction is subse- quently fetched, the updated information is obtained ... QEMU already has support for this in the common code; enable it for s390x.
