analyzer: fix const-correctness of various is_a_helper

gcc/analyzer/ChangeLog:
	* svalue.h (is_a_helper <placeholder_svalue *>::test): Make
	param and template param const.
	(is_a_helper <widening_svalue *>::test): Likewise.
	(is_a_helper <compound_svalue *>::test): Likewise.
	(is_a_helper <conjured_svalue *>::test): Likewise.
