Fix PR7054 - Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed. Users can write broken code that emits the same label twice with asm renaming, detect this and emit a fatal backend error instead of aborting. llvm-svn: 103140

; PR7054
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
