Chill type and range checks

GDB considers two Chill variables mode equivalent if the sizes of the two modes are equal. This rule applies recursively to more complex datatypes which means that complex modes are treated equivalent if all element modes (which also can be complex modes like structures, arrays, etc.) have the same size.

Range checking is done on all mathematical operations, assignment, array index bounds and all built in procedures.

Strong type checks are forced using the GDB command set check strong. This enforces strong type and range checks on all operations where Chill constructs are used (expressions, built in functions, etc.) in respect to the semantics as defined in the z.200 language specification.

All checks can be disabled by the GDB command set check off.
