#8978) * Fix VF2Layout and VF2PostLayout handling of instructions without error This commit fixes an issue in the VF2Layout and VF2PostLayout pass where the passes would potentially error in cases when a target was specified and there were instructions present without any error rates defined. In such cases the instructions should be treated as ideal (having no error) and the passes shouldn't fail. In cases where there are no error rates in the target for VF2Layout the first perfect match should be used, and for VF2PostLayout it should effectively be a no-op and not select a new layout. Fixes #8970 * Add missing comma to comment * Exit early if score is 0 Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> (cherry picked from commit 6580d96)
