sem_ch6.adb (Check_Body_To_Inline): In AAMP and VM targets use frontend inlining at all optimization levels.

2012-03-09  Javier Miranda  <miranda@adacore.com>

	* sem_ch6.adb (Check_Body_To_Inline): In AAMP and VM targets
	use frontend inlining at all optimization levels.
	* sem_util.adb (Must_Inline): In AAMP and VM targets, given that
	there is no inlining support in the backend, use also frontend
	inlining when compiling with optimizations enabled.
	* exp_ch6.adb (Expand_Call): Minor code reorganization.
