	  Compare integral AST literals without conversion to double;
	  test the full literal before simplifying unsigned comparisons, patch by Christopher Bazley.
	* src/SDCCval.c:
	  Share folding for all six comparison operators after arithmetic
	  conversion, preserving wide integer values and signedness (#4113), patch by Christopher Bazley.
