H316, I7094, NOVA, PDP1, PDP10, PDP8, SDS: Coverity singleton errors

Browse Source 
Most history routines defined a local sim_eval of the proper length, but the
erroneous ones were fixed length machines that defined an integer variable
instead of an integer array of length 1. The VAX used the global sim_eval.
The changes follow the VAX practice.
