Description:
When there are lots of operator<<s, clang produces significantly worse
diagnostics than gcc, simply because of the size of the output. This
patch limits clang to 4 overload candidates, with the ability to show
the rest by passing -fshow-all-overloads, as a first cut. We'll want to
refine that later as examples of bad behavior come up.
