  1. Prevent expr_cast hides prior error. 

    This will help not to meet confusing errors.
In issue rust-lang#5873, the error was "expected constant expr for vector length: Can't cast str to int".
It was originally "expected constant expr for vector length: Non-constant path in constant expr" (though still invalid error).
This patch make the original error to be printed.
