Finer detection of local changes of var_decl type

When the size of a var_decl changes, we want the 'equals' function for
var_decl to report that change as being a local one, not a subtype
one.

This patch fixes that.

	* src/abg-ir.cc (equals): In the var_decl overload detect size
	changes of type as being a local change.
