* Thread const correctness through a bunch of AliasAnalysis interfaces andDan Gohman2010-08-0313-103/+133

Rename the getModRefBehavior for intrinsic IDs to getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite, which happens to be implicitly convertible to bool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110155 91177308-0d34-0410-b5e6-96231b3b80d8
