[GlobalIsel] Combine ADDO (#82927) 
Perform the requested arithmetic and produce a carry output in addition
to the normal result.

Clang has them as builtins (__builtin_add_overflow_p). The middle end
has intrinsics for them (sadd_with_overflow).

AArch64: ADDS Add and set flags

On Neoverse V2, they run at half the throughput of basic arithmetic and
have a limited set of pipelines.
