[PATCH] ir: Add equality op to array_type_def::subrange_type::bound_value

[Dodji Seketeli]

Hello,

I noticed that array_type_def::subrange_type::bound_value didn't have an
equality operator.  Having one is useful in setting debugger breakpoints
to detect when bound values are being compared and analyse why.

This patch adds that operator.

	* include/abg-ir.h
	(array_type_def::subrange_type::bound_value::operator==): Declare
	new ...
	* src/abg-ir.cc
	(array_type_def::subrange_type::bound_value::operator==):
	... equality operator.

Applied to master.
