The procedure does not deal with run-time checks at all, except in a
very peculiar case, 'Pos applied to an integer type, causing multiple
checks to be generated for this case.

No functional changes.

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


	* sem_attr.adb (Eval_Attribute): Do not apply range checks in
	the case of 'Pos applied to an integer type here.
