Thanks. I'll remove the && from the one test that still has it then.
Then we can look at removing the associated code from llvm.exp and fixing
the bug. This will take a while though, at it exposes a large number of
failures that are currently hidden.

2>&1 doesn't evoke the desired behavior; the RUN line is unfortunately
interpreted by TCL rather than a regular shell. The llvm.exp bug has
allowed this and a variety of other common bourne-shell-isms to slip by
