Allow template arg names to be Inits. This is further work to
implement paste as it allows template names to participate in paste
operations.

Add a couple of utility functions to take a variable name and qualify
it with the namespace of the enclosing class and/or multiclass. This
is inpreparation for making template arg names first-class Inits.

Make the VarInit name an Init itself. We need this to implement paste
functionality so we can reference variables whose names are not yet
completely resolved.
llvm-svn: 142497
Add accessors to get Record values by Init name. This lets us look up
Record values whose names are not yet fully resolved. More work
toward paste.
llvm-svn: 142496
Fix VarListElementInit::resolveListElementReference to return a
partially resolved VarListElementInint in the case where full
resolution is not possible. This allows TableGen to make forward
progress resolving certain complex list expressions.
llvm-svn: 141315
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.
