Do not use std::move when assigning an anonymous object to a unique_ptr.

Using std::move forces an extra copy of the object.  These changes fix
-Wpessimizing-move warnings from clang.

gdb/ChangeLog:

	* ada-lang.c (create_excep_cond_exprs): Do not use 'std::move'.
	* ax-gdb.c (agent_eval_command_one): Likewise.
	(agent_eval_command_one): Likewise.
	* breakpoint.c (parse_cond_to_aexpr): Likewise.
	(parse_cmd_to_aexpr): Likewise.
	* dtrace-probe.c (dtrace_process_dof_probe): Likewise.
	* parse.c (parse_expression_for_completion): Likewise.
