[Ada] Fix stack usage increase for renaming of indexed component

This fixes an oversight in the new fold_constant_decl_in_expr function, which 
causes the code generated by the compiler for the renaming of an indexed 
component whose prefix is a constant object and whose index is not to use 
significantly more stack than needed.

Tested on x86_64-suse-linux, applied on the mainline and 5.x branch.

	* gcc-interface/trans.c (fold_constant_decl_in_expr) <ARRAY_REF>: If
	the index is not itself constant then bail out.
