[Ada] Front-end inlining in GNATprove mode

Subject: [Ada] Front-end inlining in GNATprove mode
Authentication-results: sourceware.org; auth=none

In GNATprove mode, all subprograms are candidates for front-end inlining, to
simplify proofs.  This patch extends this transformation to subprogam bodies
that do not have a previous subprogram declaration. In this case the compiler
builds a declaration, transfers aspects, if any, from body to declaration, and
attempts to create a body_to_inline, as if the Inline_Always pragma was present
on every such body.

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

	* sem_ch6.adb (Hanalyze_Subprogram_Body_Helper): In GNATprove
	mode, subprogram bodies without a previous declaration are also
	candidates for front-end inlining.
