Explicit locations: introduce probe locations

This patch adds support for probe locations and converts existing
probe linespec locations to the new location type.

	linespec for stap probe to probe location.
	* breakpoint.c (create_longjmp_master_breakpoint)

	(break_command_1): Remove local variable `arg_cp'.
	Check location type to set appropriate breakpoint ops methods.
	(trace_command): Likewise.
	* linespec.c (event_location_to_sals): Assert on probe locations.
	* location.c (EL_PROBE): Add macro definition.
	(new_probe_location, get_probe_location): New functions.
	(copy_event_location, delete_event_location, event_location_to_string)
	(string_to_event_location, event_location_empty_p): Handle probe
	locations.
	* location.h (enum event_location_type): Add PROBE_LOCATION.
	(new_probe_location, get_probe_location): Declare.
	* probe.c (parse_probes): Assert that LOCATION is a probe location.
	Convert linespec into probe location.
