Construct trace atoms with the extra field.
browser/declarative_user.m:
Print function call results using function syntax.
browser/debugger_interface.m:
browser/util.m:
Move the definition of type pred_or_func to util.m, so it can
be used by the declarative debugger as well as the external debugger.
runtime/mercury_stack_layout.h:
Update a reference to the location of type pred_or_func.
tests/debugger/declarative/Mmakefile:
tests/debugger/declarative/func_call.{m,inp,exp}:
