-// Convenience functions to get the value of an integer constant, for an
-// appropriate integer or non-integer type that can be held in an integer.
-// The type of the argument must be the following:
-//   GetSignedIntConstantValue:   signed integer or bool
-//   GetUnsignedIntConstantValue: unsigned integer, bool, or pointer
-//   GetConstantValueAsSignedInt: any of the above, but the value
-//                               must fit into a int64_t.
-// 
-// isValidConstant is set to true if a valid constant was found.
