Subject: [Ada] Undefined symbols when building GPS

This patch ensures that abort-related expansion generates the same amount of
internal entities when aborts are allowed or are being suppressed by pragma
Restriction (No_Abort_Statements).

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

2014-07-29  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch3.adb (Default_Initialize_Object): Add new variables
	Abrt_Blk and Dummy. Generate a dummy temporary when aborts are
	not allowed to ensure the symmetrical generation of symbols.
	* exp_ch7.adb (Build_Object_Declarations): Remove variables A_Expr
	and E_Decl. Add new variables Decl and Dummy. Generate a dummy
	temporary when aborts are not allowed to ensure symmertrical
	generation of symbols.
	* exp_intr.adb (Expand_Unc_Deallocation): Add new variable
	Dummy. Generate a dummy temporary when aborts are not allowed
	to ensure symmertrical generation of symbols.
