Annotate mutators that use methods that prevent mutator coalescing

Mutator coalescing reduces the overhead of visiting every module
for every mutator by calling a series of mutator methods on a
a single module in a row.  This is only valid for well-behaved
mutators.  Add methods on MutatorHandle that allow annotating
mutators that are not well behaved, and use that to prevent
coalescing mutators.
