* !foreach on lists didn't evaluate operands of the RHS operator. This made nested operators silently fail. * A typo in the code could result in a wrong value substituted for an operation which produced a false '!foreach requires an operator' error. * Keep recursion over the DAG within ForeachHelper. This simplifies things a bit as we no longer need to pass the Type around in order to prevent recursion. Differential Revision: https://reviews.llvm.org/D43083 llvm-svn: 324758
