[patch] genattrtab.h: Remove four unused macros.

[Kazu Hirata <kazu at cs dot umass dot edu>]

Hi,

Attached is a patch to remove four unused macros.

ATTR_FUNC_UNITS
ATTR_BLOCKAGE

  These two do not appear anywhere in the source code except in their
  own definitions.

ATTR_NEGATIVE_OK
ATTR_UNSIGNED

  These macros are used in conditionals, but they are never assigned
  to variables.

They were introduced with

http://gcc.gnu.org/ml/gcc-cvs/2003-07/msg00362.html

The last real uses of these macros were moved by

http://gcc.gnu.org/ml/gcc-cvs/2004-07/msg01020.html

Tested on i686-pc-linux-gnu.  OK to apply?

	* genattrtab.c (attr_desc): Remove negative_ok and unsigned_p.
	(check_attr_value, write_attr_get, write_expr_attr_cache,
	find_attr, make_internal_attr): Don't reference negative_ok or
	unsigned_p.
	* genattrtab.h (ATTR_NEGATIVE_OK, ATTR_UNSIGNED,
	ATTR_FUNC_UNITS, ATTR_BLOCKAGE): Remove.
	(ATTR_STATIC): Adjust the value.
