Fergus Henderson 5e0cfaf6bd Fix a bug where MR_deep_copy() was crashing when copying closures

Estimated hours taken: 3
Branches: main, release

Fix a bug where MR_deep_copy() was crashing when copying closures
for polymorphic predicates.

runtime/mercury_layout_util.h:
runtime/mercury_layout_util.c:
	Add MR_materialize_closure_typeinfos(),
	for use by mercury_deep_copy_body.h.

runtime/mercury_deep_copy.c:
	#include mercury_layout_util.h, for MR_materialize_closure_typeinfos().

runtime/mercury_deep_copy_body.h:
	Fix a bug: when copying closures, use MR_materialize_closure_typeinfos()
	to get the type_infos for the already-applied closure arguments
	from the closure itself, rather than trying to get them from
	the arguments of the typeinfo for the closure (the latter holds
	the type-infos for the yet-to-be-applied arguments, not the
	already-applied arguments).

tests/hard_coded/Mmakefile:
tests/hard_coded/copy_pred_2.m:
tests/hard_coded/copy_pred_2.exp:
	Add a test case.
