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

"Allow LICM to sink or lift loads from constant memory. Also add a test case for this. This allows instructions like loads from global variables declared to be constant to be moved out of loops."
