[PATCH 1/5] Remove useless types from parser

[Tom Tromey]

This removes some useless yacc type declarations from the parser.
We'll add types back to a couple of these later, but this approach
makes the series more obviously correct.

	* c-exp.y (func_mod, direct_abs_decl, abs_decl, ptr_operator):
	Remove %type.
