Title: Add feature for testing diagnostic bugs

Issue 8354 - Some missing "import std.math to use ^^ operator" error messages
Issue 8559 - void and function type prints redundant error message with init property

In fail_compilation tests, now can use ERROR_MSG parameter for testing error messages.
