Convert the uses of '|&' to use '2>&1 |' instead, which works on old versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. llvm-svn: 159544

Require intervals in the range metadata to be in a canonical form: They must be non contiguous, non overlapping and sorted by the lower end. While this is technically a backward incompatibility, every frontent currently produces range metadata with a single interval and we don't have any pass that merges intervals yet, so no existing bitcode files should be rejected by this. llvm-svn: 157741

Fix typos noticed by Benjamin Kramer. Also make the checks stronger and test that we reject ranges that overlap a previous wrapped range. llvm-svn: 157749
