I only remembered to add DEF_VEC_A handlgin to gengtype.c a second after committing the previous patch [1].

Here it is, done as a follow up. With some luck, this will be short-lived code because of the C++ conversion.

Bootstrapped and regtested on x86_64 linux. OK for trunk?

	* gengtype.h (enum gc_vec_type_kind): New.
	List individual vector kinds in the token codes.
	* gengtype-lex.l: Handle DEF_VEC_A, DEF_VEC_O, DEF_VEC_P,
	DEF_VEC_I individually.
	* gengtype-parse.c (token_names): Replace "DEF_VEC_[OP]" with
	individual vector token names.
	(def_vec): handle vector token types separately.
	(parse_file): handle the new vector token types.
	* gengtype.c (note_def_vec): remove is_scalar argument, introduce
	vec_type_argument instead.  Create GTY option and resolve the
	vector element type according to vec_type_argument value.
