tree-optimization/116481 - avoid building function_type[]

The following avoids building an array type with function or method
element type during diagnosing an array bound violation as this
will result in an error, rejecting a program with a not too useful
error message.  Instead build such array type manually.

	PR tree-optimization/116481
	* pointer-query.cc (build_printable_array_type):
	Build an array types with function or method element type
	manually to avoid bogus diagnostic.

	* gcc.dg/pr116481.c: New testcase.
