New Revision: 99369

URL: http://llvm.org/viewvc/llvm-project?rev=99369&view=rev
Log:
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.
