Fix gcc optimization level for debug builds

This fixes a minor "bug" I happened to notice.  For gcc, we were setting
the optimization level to -O2 for all builds instead of just for
CMAKE_BUILD_TYPE=release.  Debug builds should be -Og or -O0, otherwise
a debugger is not useful (source code no longer matches up 1-to-1 with
executable), defeating the purpose of CMAKE_BUILD_TYPE=debug.  The comment
makes clear that the intention was to lower the optimization in
release builds from -O3 to -O2, but the way this was done also raised
the optimization of debug builds (as well as all other build types) from
-Og to -O2
