This is the first of a number of changes designed to generalise
MCWin64EHInstruction to support different target architectures. An ordered set
(vector) of these instructions is saved per frame to permit the emission of
information for Windows NT style unwinding. The only bit of information which
is actually target specific here is the Opcode for the unwinding bytecode. The
remainder of the information is simply generic information that is relevant to
the Windows NT unwinding model.
Remove the accessors for the fields, making them const and public instead. Sink
the knowledge of the alias'ed name into the single source and sink a single-use
check method into the use.
