-// This defines the Use class.  The Use class represents the operand of an
-// instruction or some other User instance which refers to a Value.  The Use
-// class keeps the "use list" of the referenced value up to date.
-//
-// Pointer tagging is used to efficiently find the User corresponding
-// to a Use without having to store a User pointer in every Use. A
-// User is preceded in memory by all the Uses corresponding to its
-// operands, and the low bits of one of the fields (Prev) of the Use
-// class are used to encode offsets to be able to find that User given
-// a pointer to any Use. For details, see:
