  dfmc: Add a primitive to limit <method> type punning

The method-list construction code in the dylan library sometimes
returns a <method> in place of a <single-method-engine-node> in
situations where the calling conventions are sufficiently
similar. This commit adds a primitive to help determine when this is
the case for the particular back-end.

* sources/dfmc/modeling/primitives.dylan
  (primitive primitive-callable-as-engine-node?): New primitive
   definition.

* sources/dfmc/modeling/namespaces.dylan
  (module dylan-primitives): Export primitive-callable-as-engine-node?.

* sources/dfmc/harp-cg/harp-primitives.dylan
  (op--true): Emitter for always-true boolean conditions.
  (primitive primitive-callable-as-engine-node?): New HARP primitive
   implementation, always returns #t.

* sources/lib/run-time/run-time.h
  (primitive_callable_as_engine_nodeQ): New C primitive implementation,
   always returns #t.

* sources/dfmc/llvm-back-end/llvm-primitives-lambda.dylan
  (primitive-callable-as-engine-node?): New LLVM primitive
   implementation, returning #t for methods that are instances of
   <keyword-method> and #f otherwise.
