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.

Rafael Espindola 7161661863 Move the loads after the calls so that the fix for 
PR10292 doesn't show that the loads don't alias
the allocas.

Dan Gohman 02538ac4d3 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.

Dan Gohman 109561845b 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.

Dan Gohman bd33dab633 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.

Dan Gohman 00ef93258a 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.

Dan Gohman 84f90a387d 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.
