  Hello,

While debugging some issues, I felt the need to easily get the type-id
from a given ir::type_base* from within the debugger.

I have thus added this new environment::get_type_id_from_type member
function.

	* include/abg-ir.h (environment::get_pointer_type_id_map): Declare
	...
	* src/abg-ir.cc (environment::get_pointer_type_id_map): ... this
	new member function.
