Added -serial-ir command line option (#664)

* Added -serial-ir option, to make generateIR always serialize in and out before further processing. Testing out serialization, and adding a kind of 'firewall' between compiler front end and backend.

* Reduce peak memory usage, by discarding IR when stored in serialized form.
Typo fix.
