"Unexpected tree in genLoad" compiler crash when invoking super.+(String)

[scabug]

Try to compile this:

class A {
  super.+("")
}

and you'll get this:

Exception in thread "main" java.lang.Error: Unexpected tree in genLoad: A.super at: source-../scala/test/files/neg/supper-to-breakfast.scala,line-2,offset=12

Subsuming into #4987.

Reopening because the subsumption ticket seems to have been fixed as a consequence of error trees, but this wasn't.
