	* opt.ads (Expand_Nonbinary_Modular_Ops): New flag.
	* exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
	Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
	other back-ends can also benefit from the front-end expansion. Remove
	test for Modify_Tree_For_C in all callers to better share code.
	* gnat1drv.adb (Adjust_Global_Switches): Set
	Expand_Nonbinary_Modular_Ops when generating C code.

	* exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
	parameter becomes invisible after analyzing the loop, which has been
	rewritten as a while-loop.

	* vxaddr2line.adb: Revise and enhance for new ports, remove dead ports,
	and update for 64bit ports.
