Compare the given set of language options against an existing set of language options.

Parameters
DiagsIf non-NULL, diagnostics will be emitted via this engine.
AllowCompatibleDifferencesIf true, differences between compatible language options will be permitted.
Returns

Check the preprocessor options deserialized from the control block against the preprocessor options in an existing preprocessor.

Parameters
DiagsIf non-null, produce diagnostics for any mismatches incurred.
ValidationIf set to OptionValidateNone, ignore differences in preprocessor options.
