Chandler Carruth 5da53436d5 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.

Duncan Sands 5ec65765e6 Revert commit 131781, to see if it fixes the x86-64 dragonegg buildbot. 
Original log message:
When BasicAA can determine that two pointers have the same base but
differ by a dynamic offset, return PartialAlias instead of MayAlias.
See the comment in the code for details. This fixes PR9971.
