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: opt -S -O1 -debug-pass=Arguments 2>&1 \| FileCheck %s`

Teach the 'opt' tool about '-Os' and '-Oz', corresponding to the Clang options, to enable easier testing of the innards of LLVM that are enabled by such optimization strategies. Note that this doesn't provide the (much needed) function attribute support for -Oz (as opposed to -Os), but still seems like a positive step to better test the logic that Clang currently relies on.
