Add return/report/warnings_as_errors compile options

[ghost]

It would be highly useful to add the same return/return_warnings/return_errors/report/report_warnings/report_errors/warnings_as_errors options as available in compile:file and leex:file for neotoma's own errors/warnings.

To be clear, options passed to compile:file of course support warnings_as_errors, and the ticket is about warnings emitted by this compiler.

@Tuncer The refactoring I'm working on (long and detailed and difficult) will include both warnings and errors. I'll be sure to include this.

Sounds good. For reference, the options are: return, return_warnings, return_errors, report, report_warnings, report_errors, and warnings_as_errors.
