libcc1 base API: bump set_arguments; add set_driver_filename, set_triplet_regexp

for  include/ChangeLog

	* gcc-interface.h (enum gcc_base_api_version): Update comment
	for GCC_FE_VERSION_1.
	(struct gcc_base_vtable): Rename set_arguments to
	set_arguments_v0.  Add set_arguments, set_triplet_regexp and
	set_driver_filename.

for  libcc1/ChangeLog

	* libcc1.cc (libcc1): Add class compiler with field compilerp,
	class compiler_triplet_regexp and class
	compiler_driver_filename.
	(libcc1::libcc1): Initialize compilerp.
	(libcc1::~libcc1): Delete compilerp.
	(libcc1::compiler::find, libcc1::compiler_triplet_regexp::find)
	(libcc1::compiler_driver_filename::find): New methods.
	(libcc1_set_arguments): Remove parameter triplet_regexp.
	(libcc1_set_triplet_regexp, libcc1_set_driver_filename)
	(libcc1_set_arguments_v0): New functions.
	(vtable): Use libcc1_set_arguments_v0, add
	libcc1_set_arguments, libcc1_set_triplet_regexp and
	libcc1_set_driver_filename.
