9c42bcf2ca Resolve Record Names
When resolving Record values, be sure to update the Record name as it
may contain references to the value.

f628204262 Allow Names Changes on Unregistered Records
Add Record names to be changed even on Records that aren't yet
registered.  We need to be able to do this for paste functionality
because we do not want to register def names before they are unique
and that can only happen once all paste operations are done.  This
change lets us update Record names formed by paste operations and
register the result later.

implement paste as it allows template names to participate in paste

multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.

a6d442e651 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.

6da674cda1 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.

cedaae125e Allow Operator Arguments
When resolving an operator list element reference, resolve all
operator operands and try to fold the operator first.  This allows the
operator to collapse to a list which may then be indexed.

Before, it was not possible to do this:
class D<int a, int b> { ... }
class C<list<int> A> : D<A[0], A[1]>;
class B<list<int> b> : C<!foreach(...,b)>;

Now it is.

f987425657 tblgen: add preprocessor as a separate mode
This patch adds a preprocessor that can expand nested for-loops for
saving some copy-n-paste in *.td files.

The preprocessor is not yet integrated with TGParser, and so it has
no direct effect on *.td inputs.  However, you may preprocess an td
input (and only preprocess it).

To test the proprecessor, type:
  tblgen -E -o $@ $<
