Tablegen was unable to determine that param loads/stores were actually
reading or writing from memory.  I think this isn't a problem in
practice for param stores, because those occur in a block right before
we make our call.  But param loads don't have to at the very beginning
of a function, so should be annotated as mayLoad so we don't incorrectly
optimize them.
