compiletest: //~ ERROR should be interpreted as applying to all revisions #56279
Description
Spawned off of https://github.com/rust-lang/rust/pull/56244/files#r236635792
Right now, you have to write explicit //[rev]~ ERROR annotations for each revision rev in a given test. This is true even when all of the revisions can use identical annotations.
We should change compiletest so that occurrences of //~ ERROR are still parsed and are treated as synonymous for a copy of that same annotation for every revision in the // revisions: set.

In some situations it would also have been nice to be able to specify a set of revisions like
//[revA revB]~ ERROR.tmiasko commentedon Feb 1, 2022
Since #66524
//~ ERRORapplies to all revisions, and//[A,B]~ ERRORto revisionsAandB.
