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 2012-07-03 02:37:59 +08:00			`# RUN: not llvm-mc -triple i386-unknown-unknown %s 2>&1 \| FileCheck %s`
