This patch adds support for the ARMv8-M Security Extensions
'cmse_nonsecure_entry' attribute. In this patch we implement the
attribute handling and diagnosis around the attribute. See Section 5.4
of ARM®v8-M Security Extensions
(http://infocenter.arm.com/help/topic/com.arm.doc.ecm0359818/index.html).
