49589f0d0e 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.

aecfdd3068 Move the loads after the calls so that the fix for 
PR10292 doesn't show that the loads don't alias
the allocas.

c1be92f3bb Make BasicAliasAnalysis a normal AliasAnalysis implementation which 
does normal initialization and normal chaining. Change the default
AliasAnalysis implementation to NoAlias.

Update StandardCompileOpts.h and friends to explicitly request
BasicAliasAnalysis.

Update tests to explicitly request -basicaa.

907857d746 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.

3dcc91ee8c 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.

9e86f4364b Remove interprocedural-basic-aa and associated code. The AliasAnalysis 
interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.

21de4c0daf Remove context sensitivity concerns from interprocedural-basic-aa, and 
make it more aggressive in cases where both pointers are known to live
in the same function.
