[issue2506] Add mechanism to disable optimizations

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

In general, it is hard to define what is an optimization, and what is part of the compiler.

The original request was to disable optimizations that changed observable behavior w.r.t. line numbers.

All optimizations now respect line numbers, so proposed mechanism would be pointless.
