// The layout of mixins in a host class:
// 1. Each mixin occupies a continuous segment in the data arrays of the host.
// The ranges of the segments are stored in DaoClass::ranges;
// 2. If the mixin contains other mixins, those mixins occupy segments preceding
// the segment for this mixin;
// 3. The segments for the direct mixins of the host are arranged in the same
// order as the mixins;
//
// For example, there are the following mixins:
// class AA { var x = 1 }
// class BB { var x = 1 }
// class CC ( AA, BB ) { var x = 1 }
// class DD ( CC, AA ) { var x = 1 }
// The mixin layout for CC:
// CC_Header, AA_Header, AA_Data, BB_Header, BB_Data, CC_Data
// The mixin layout for DD:
// DD_Header, AA_Header, AA_Data, BB_Header, BB_Data, CC_Header, CC_Data, DD_Data
//
// Where XX_Header are the data fields that are always placed at the header
// of the data array. For example, XX_Header for class constants contains
// two fields: one for the class itself, the other for the class constructor(s);
// XX_Header for class static variables is empty; and XX_Header for class
// instance variables contains only the field for the "self" variable.
// And XX_Data constains the mixin's own data which are not from its
// component mixins or from its paraent classes (actually only classes
// without parent classes can be used as mixins).
//
//
// To mix a mixin in the host class, the mixin (and its component mixins if any)
// are properly arranged in the host class with layouts described above.
// The non-trivial part is the update of variable types and the methods
// that are added to the host class from the mixin. To update the types,
// the type for the mixin are all replaced with the type for the host class.
//
// The update of methods involves three major steps:
// 1. Update the routine signature type, local variable types and the static
// variable types;
// 2. Update the lookup table of the host class for the data from the mixins,
// which is done by mapping the indices for the mixin data arrays to the
// indices for the host data arrays;
// 3. Update the method code (VM instructions) such that operands involving
// class or class instance data are properly mapped from the indices for
// the mixin data arrays to the indices for the host data arrays.
