This patch fixes the compiler to that class-wide preconditions on primitive
operations of interfaces are not checked at run time when the Assertion_Policy
indicates that they should be ignored. This is required by the RM.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* exp_disp.adb (Build_Class_Wide_Check): Return early if the
	precondition is supposed to be ignored.
