detecting GTY'ed types and typedefs; replace with simple

simplify, relying on read_input_list to set up the bitmaps.
(main): Arguments are no longer unused. Check for correct number
of command line arguments, set srcdir and srcdir_len, then call
read_input_list, before doing anything else. No need to worry
about duplicates in main loop.
* configure.ac: Simplify the calculation of all_gtfiles.
Put language tags in there. Don't set or substitute
all_gtfiles_files_langs or all_gtfiles_files_frags.

takes a file on its command line with a much simpler format.

Consolidate type definitions at the top of the file.
(xvasprintf): Delete.

(create_field_all, create_field_at): New functions.
(create_field): Now a thin wrapper around create_field_all.
(create_optional_field): Rename create_optional_field_ and add

(optionseq): Consolidate productions from option here so we
can use the first argument to create_option.
From-SVN: r123233
* gengtype-lex.l: Distinguish unions from structures in the
token type. Don't call find_structure; return the tag as a string.
* gengtype-yacc.y: Add new token types ENT_TYPEDEF_UNION and ENT_UNION.
Type of these, ENT_TYPEDEF_STRUCT, and ENT_STRUCT is string.
Reorganize typedef_struct production accordingly.
Use create_nested_ptr_option.

or scalar_nonchar as appropriate.
(adjust_field_type): Look at scalar_is_char boolean to decide whether
to use string_type.
(throughout): Use scalar_nonchar instead of calling create_scalar_type,
whenever possible.
(main): Initialize scalar_char and scalar_nonchar before calling
gen_rtx_next.
* gengtype-lex.l: Adjust for removal of second argument to
create_scalar_type. Use yylval.s instead of yylval.t when
returning SCALAR.
* gengtype-yacc.y: Type of SCALAR is string. Call
create_scalar_type from type:SCALAR rule. Adjust for removal of
second argument to create_scalar_type.
From-SVN: r123231
