Detailed Description

A class for handling the various dump_* calls.

In particular, this class has responsibility for consolidating
the "dump_*" calls into optinfo instances (delimited by "dump_*_loc"
calls), and emitting them.

Putting this in a class (rather than as global state) allows
for selftesting of this code.
