c-pragma.h: Define HANDLE_GENERIC_PRAGMAS if REGISTER_TARGET_PRAGMAS is defined.

	* c-pragma.h: Define HANDLE_GENERIC_PRAGMAS if
	REGISTER_TARGET_PRAGMAS is defined.  Duplicate some
	definitions from cpplib.h.
	* cpplib.h: Don't typedef struct cpp_reader if c-pragma.h has
	already done it.
	* tm.texi: Document HANDLE_PRAGMA as no longer supported.  Add
	documentation for REGISTER_TARGET_PRAGMAS.

	* c-lex.c: Include cpplib.h before c-pragma.h.  Define a
	default-pragma callback to implement -Wunknown-pragmas if
	USE_CPPLIB.
	* c-parse.in: Move all includes to top of file.
	* c-pragma.c: Include cpplib.h before c-pragma.h.  Include
	tm_p.h.
	(dispatch_pragma): Put the namespace in the -Wunknown-pragmas
	warning.
	(init_pragma): If REGISTER_TARGET_PRAGMAS is defined, call it.

	* arm.h, arm-protos.h, arm.c,
	  c4x.h, c4x-protos.h, c4x.c,
	  h8300.h, h8300-protos.h, h8300.c,
	  i370.h, i370-protos.h, i370.c,
	  i960.h, i960-protos.h, i960.c,
	  sh.h, sh-protos.h, sh.c,
	  v850.h, v850-protos.h, v850.c: Convert HANDLE_PRAGMA-based
	pragmata scheme to use REGISTER_TARGET_PRAGMAS instead.

	* d30v.h: Don't mention HANDLE_PRAGMA in comment.  Add
	multiple include guard.
	* i370.md (untyped_call): Use GEN_CALL.
	(umodsi3): Remove unused variable.
	* sh/elf.h: Don't undef HANDLE_SYSV_PRAGMA.
	* v850.c (output_move_single, output_move_double): Constify
	return value.
	(print_operand): Constify a char *.
	* v850.h (struct small_memory_info): Constify name member.
