add support for a new flag: -fdump-linearize[=only]

The effect of this flag is to dump the IR just after the
linearization, before any simplification, and to stop
further processing if '=only' is given as argument.

The motivation of this flag is of course for debugging,
to be able to inspect the raw result of the linearization,
undisturbed by an simplification.
