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.

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 $@ $<
