[dart2js] hashCode stability to improve repeatability

The default Object.hashCode is different on every run, so avoid using it for MemberEntity.hashCode.

Using a consistent (if arbitrary) hashCode appears to fix issue 34527
and also makes the *.js.map files consistent.
We also sort instructions in SsaCodeMotion to make order less sensitive to unrelated changes.

We might still want to impose a canonical ordering for map files, e.g. minified map file entries might be sorted by name.
