Revert the test moves from 176733. Use "REQUIRES: asserts" instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176873 91177308-0d34-0410-b5e6-96231b3b80d8

; REQUIRES: asserts
Add new RegionInfo pass. The RegionInfo pass detects single entry single exit regions in a function, where a region is defined as any subgraph that is connected to the remaining graph at only two spots. Furthermore an hierarchical region tree is built. Use it by calling "opt -regions analyze" or "opt -view-regions". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109089 91177308-0d34-0410-b5e6-96231b3b80d8

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
