Rewrite reportIntrospectionError calls

Once upon a time, Prepack didn't have a real error-handling story besides just throwing an exception. From this time, there are still a ton of reportIntrospectionError calls in the code base.

They should all be rewritten, one by one (separate pull-requests, please) into something like the following.

    let error = new CompilerDiagnostic("appropriate error message", referenceToSourceLocation, "PPxxxx", "FatalError");
    realm.handleError(error);
    throw new FatalError();

Where PPxxxx should be the next currently unused error code; check https://github.com/facebook/prepack/wiki/Prepack-diagnostics for all currently defined error code.

• Create a new wiki page with the PP error number as its name.
• Add a link to it from the page that lists all error numbers.
