Switch SDTUnaryArithWithFlags to being modeled as a two-result
ISD node. The only change in the generated isel code are comments
like:
< // Src: (X86dec_flag:i16 GR16:i16:$src)
---
> // Src: (X86dec_flag:i16:i32 GR16:i16:$src)
because now it knows that X86dec_flag returns both an i16 (for the result)
and an i32 (for EFLAGS) in this case. Wewt.
