Speed up SCCP substantially by processing overdefined values quickly.  This
patch speeds up SCCP by about 30-40% on large testcases.

This version takes about 1s longer than the previous one (down to 2.35s),

This eliminates an N*N*logN algorithm from the loop simplify pass, replacing
it with a much simpler and faster alternative.  In a debug build, this reduces
gccas time on eon from 85s to 42s.

now send references to ostreams instead of pointers.  Sending pointers to
ostreams will print their addresses.
