Let str::replace take a pattern

It appears this was left out of RFC #528 because it might be useful to
also generalize the second argument in some way.  That doesn't seem to
prevent generalizing the first argument now, however.

This is a [breaking-change] because it could cause type-inference to
fail where it previously succeeded.
