This implements a few Ada unary operations, using the existing
unop_operation template class.

gdb/ChangeLog
2021-03-08  Tom Tromey  <tom@tromey.com>

	* ada-lang.c (ada_unop_neg, ada_atr_tag, ada_atr_size, ada_abs):
	No longer static.
	* ada-exp.h (ada_neg_operation, ada_atr_tag_operation)
	(ada_atr_size_operation, ada_abs_operation): New typedefs.
