If an exception is to be raised, the destination fp register should be unmodified. The current implementation is incorrect, in that double results will be written back before calling gen_helper_check_ieee_exceptions, despite the placement of gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[]. We can simplify the entire implementation by having each FPOp helper call check_ieee_exceptions. For the moment this requires that all FPop helpers write to the TCG global cpu_fsr, so remove TCG_CALL_NO_WG from the DEF_HELPER_FLAGS_*.
