[compiler] Add fast path for simple parallel moves Most parallel moves do not actually require the heavy analysis in the GapResolver since there is no overlap between source and destination registers. Handle some of these cases by a fast-path to avoid the quadratic behaviour in the general case. The fast path is taken for about 2/3 of the non-empty parallel moves on wasm workloads.
