[Ada] Minor cleanup in Expand_Call_Helper

2020-06-18  Eric Botcazou  <ebotcazou@adacore.com>

gcc/ada/

	* exp_ch6.adb (Expand_Call_Helper): Remove superfluous calls
	to Relocate_Node and merge calls to Analyze and Resolve in a
	couple of places.  Do not attempt to generate a range check
	for an actual parameter against the formal's type of a derived
	subprogram after generating a conversion to the formal's type
	of the parent subprogram.
