Alyssa Rosenzweig f688364bf2 IR: Add AddNZCV/SubNZCV op ...

AddNZCV is a new op to return the NZCV for an addition directly, which lets us
skip software flag calculation in some cases. In the future it would be nice to
fuse this into the Add itself as a second destination to avoid repeating the
addition, but that's a very involved change and right now I'm building FEX on an
old Chromebook because my M1 kernel is FUBAR.

Similarly, SubNZCV returns flags for Sub. This has the extra twist of needing to
invert the carry bit due to the inverted definition between arm64 and x86_64.
