	(be_builder::build): Parse the priority & pass it to be_derived_probe.
	(be_derived_probe_group::emit_module_init, emit_module_exit): Sort the
	probe list by priority before emitting any code.
	(register_standard_tapsets): Add new begin/end variants.
	* parse.cxx (parser::parse_literal): Allow negative numeric literals,
	by checking for a '-' unary operator right before a number.
