Estimated hours taken: 4

Add four new ports: entering the condition of an if-then-else, entering a
negation, and leaving a negation via success or failure. If --trace-decl
is enabled, generate these events, which the declarative debugger needs
in order to properly delimit negated contexts (which should cause a switch
from wrong answer to missing answer diagnosis and vice versa).

compiler/llds.m:
runtime/mercury_trace_base.h:
browser/debugger_interface.m:
	Add the new event types.

compiler/llds_out.m:
	Print the new event types.

compiler/trace.m:
	Provide predicates to generate code for the new events if --trace-decl
	is set.

	Separate out the code for dealing with the trace_info data type.

compiler/ite_gen.m:
	Call trace.m to (conditionally) generate code for the new events.

trace/mercury_trace_internal.c:
	Print the names of the new ports when events of those types happen.
