[Bug tree-optimization/18374] New: Argument and return value marshalling at tree level

["nathan at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This is a catch-all report to mention that we should really be doing ABI
mandated argument and return value marshalling at the tree level. These
operations can involve sign/zero extension (at the very least) and should be
exposed to the tree optimizers.
