dump-ir: allow to skip the optimization pass(es)
For experimenting with some optimization and the linearization
process, it's useful to see the raw result, without any kind
of optimization.
This patch test PASS_OPTIM (-foptim-{enable,disable}) to see
if the whole optimization process can be skipped.
Note: ideally, this should be coupled with -O0 but this
could create problems with the 'sparse' tools when used
on file wit an optimization level of 0 (since the sparse
tools depends on the optimization for the context checking
to be accurate and in general diagnostics also need
at least basic optimization).
