Topic: wasmtime / PR #5162 Remove trapif and trapff

elliottt opened PR #5162 from trevor/remove-trap-iflags-instructions to main:

WIP.

This branch removes the trapif and trapff instructions, in favor of using an explicit comparison and trapnz. This moves us closer to removing iflags and fflags, but introduces the need to implement instructions like iadd_cout in the x64 and aarch64 backends.

The part of the comment starting here should still be kept - the new uadd_overflow_trap still uses the condition code mask described here. The comment should probably just be moved there.
