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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103140 91177308-0d34-0410-b5e6-96231b3b80d8 2010-05-06 00:05:37 +00:00			`; 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159544 91177308-0d34-0410-b5e6-96231b3b80d8 2012-07-02 18:37:59 +00:00			`; RUN: not llc %s -o - 2>&1 \| grep "'_foo' label emitted multiple times to assembly"`
