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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116720 91177308-0d34-0410-b5e6-96231b3b80d8 2010-10-18 18:04:47 +00:00			`; RUN: opt < %s -basicaa -aa-eval -print-all-alias-modref-info -disable-output \`
