However, it has different rules for silencing an SNaN: (1) msb is cleared and (2) msb-1 must be set if the fraction is now zero, and (implementation defined) may be set always. I haven't checked real hardware but chose the set always alternative because it's easy and within spec.

Execution of a nullified insn clears the PSW[N] bit. This adds a generic framework for branching over nullified insns, or for sufficiently simple insns, transforming the writeback of the result to a conditional move. In the process, we want to be able to represent PSW[N] as a TCG condition, which implies management of the related tcg temps.
