Remove the strange conjoining of debug and optimization flags.

Previously a build had optimizations disabled completely when debug info was
emitted. But there are many reasons to use optimized builds with debug symbols
(running under valgrind, against afl, with Asan/Ubsan, in prod, etc).

And personally I find even debugging at -O2 or -O3 is fine most of the time and
worth it for the speed. Use the (now documented!) --no-optimizations flag if no
optimization is desired while debugging.

This also removes the distinction between library and application compile flags;
there is a single optimization level that is probably good enough for everything.

On Win32 it removes definding _CONSOLE for the application. This seems to be
some mythical value that may have been required at some point, but is not
documented anywhere I can find. Who knows what VC thinks, hoping I don't have to
add this back. It also drops defining `EBUG` which is what happens when you
tell cl.exe to '/DEBUG'. LOL.
