Hal Finkel 4cb3366de0 BasicAA should look through functions with returned arguments ...

Motivated by the work on the llvm.noalias intrinsic, teach BasicAA to look
through returned-argument functions when answering queries. This is essential
so that we don't loose all other AA information when supplementing with
llvm.noalias.
