optimisation: switch back to Og for debugging
...
O0 is catastrophically slow for some of our projects. Don't
unconditionally use O0.

This works around an ICE with libcruft-util's coord classes and GCC's
trunc_int_for_mode.

optimsation: prefer -O0 over -Og
...
Og optimises out too many variables to be useful in a large percentages

introduce a new flag.
