- TSPHP-681 Change type hierarchy of scalar types
-- new components
- TSPHP-820 Falseable types
-- added modifier to the grammar
-- modified tests and added new ones
- TSPHP-832 cast to falseable or nullable types - expression multiple times evaluated
- TSPHP-833 move output logic for cast to helper class
-- created ICastHelper
-- removed several tests in integration.coverage.CastOperator because the code is simplified (coverage is not necessary any more)
- TSPHP-834 cast from mixed to scalar needs test
-- some preparations done, not yet fully implemented
