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

The two-callsite form of AliasAnalysis::getModRefInfo is documented to return Ref if the left callsite only reads memory read or written by the right callsite; fix BasicAliasAnalysis to implement this. Add AliasAnalysisEvaluator support for testing the two-callsite form of getModRefInfo. llvm-svn: 110270

Implement AccessesArguments checking in the two-callsite form of BasicAA::getModRefInfo. This allows BasicAA to say that two memset calls to non-aliasing memory locations don't interfere. llvm-svn: 110393

The trouble with testing for "ModRef" and "NoModRef" is that one is a suffix of the other, and FileCheck accepts superstrings. Adjust the output to avoid this problem. llvm-svn: 110280
