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: llvm-mc --disassemble %s -triple=arm-apple-darwin9 2>&1 \| grep "invalid instruction encoding"`

Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter. This new disassembler can correctly decode all the testcases that the old one did, though some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in operand checking as the old one was. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137144 91177308-0d34-0410-b5e6-96231b3b80d8 2011-08-09 20:55:18 +00:00			`# 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0`
