[COMMITTED] ada: Fix spurious warning on Inline_Always and contracts

[Marc Poulhiès]

From: Piotr Trojanek <trojanek@adacore.com>

Warnings about pre/postconditions being ignored with Inline_Always were
only true for the obsolete frontend inlining. With the current backend
pre/postconditions work fine with Inline_Always.

gcc/ada/

	* sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram): Only
	emit warning when frontend inlining is enabled.

Tested on x86_64-pc-linux-gnu, committed on master.
