David Greene db10e69138 Make Template Arg Names Inits
Allow template arg names to be Inits.  This is further work to
implement paste as it allows template names to participate in paste
operations.

David Greene 3ca42126f5 Let SetValue Take and Init Name
Convert SetValue to take the value name as an Init.  This allows us to
set values for variables whose names are not yet fully resolved.

David Greene 33f619971f Remove Multidefs
Multidefs are a bit unwieldy and incomplete.  Remove them in favor of
another mechanism, probably for loops.

David Greene 47a665e93e Prefix Template Arg Names with Multiclass Name
For consistency, prefix multiclass template arg names with the
multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.

David Greene 2ac084dbb2 Process Multidefs
Process each multidef declared in a multiclass.  Iterate through the
list and instantiate a def in the multiclass for each item, resolving
the list item to the temporary iterator (possibly) used in the
multidef ObjectBody.  We then process each generated def in the normal
way.

David Greene dd1eb61298 Parser Multidef Support
Add parser support to recognize multidefs.  No processing on the
multidef is done at this point.  The grammar is:

MultiDef = MULTIDEF ObjectName < Value, Declaration, Value > ObjectBody

The first Value must be resolveable to a list and the second Value
must be resolveable to an integer.  The Declaration is a temporary
value used as an iterator to refer to list items during processing.
It may be passed into the ObjectBody where it will be substituted with
the list value used to instantiate each def.

David Greene db44597494 Refactor Multiclass Def Processing
Move the code to instantiate a multiclass def, bind its arguments and
resolve its members into three helper functions.  These will be reused
to support a new kind of multiclass def: a multidef.
