Introduce CP_OPERATOR_STR/CP_OPERATOR_LEN and use throughout

Move LENGTH_OF_OPERATOR from cp-support.c to cp-support.h so we can
use it elsewhere.  Since there's already
CP_ANONYMOUS_NAMESPACE_STR/CP_ANONYMOUS_NAMESPACE_LEN there, follow
the same naming pattern for the new symbols.

gdb/ChangeLog:
2017-07-17  Pedro Alves  <palves@redhat.com>

	* c-exp.y (operator_stoken): Use CP_OPERATOR_LEN and
