PR target/82628
* config/i386/i386.md (addcarry<mode>, subborrow<mode>): Change
patterns to better describe from which operation the CF is computed.
(addcarry<mode>_0, subborrow<mode>_0): New patterns.
* config/i386/i386.c (ix86_expand_builtin) <case handlecarry>: Pass
one LTU with [DT]Imode and another one with [SD]Imode. If arg0
is 0, use _0 suffixed expanders instead of emitting a comparison
before it.
