tools/memory-model: Make judgelitmus.sh detect hard deadlocks
If a litmus test specifies "Result: Never" and if it contains an
unconditional ("hard") deadlock, then running checklitmus.sh on it will
not flag any errors, despite the fact that there are no executions.
This commit therefore updates judgelitmus.sh to complain about tests
with no executions that are marked, but not as "Result: DEADLOCK".

tools/memory-model: Make judgelitmus.sh identify bad macros
Currently, judgelitmus.sh treats use of unknown primitives (such as
srcu_read_lock() prior to SRCU support) as "!!! Verification error".
This can be misleading because it fails to call out typos and running
a version LKMM on a litmus test requiring a feature not provided by
that version. This commit therefore changes judgelitmus.sh to check
for unknown primitives and to report them, for example, with:
'!!! Current LKMM version does not know "rcu_write_lock"'.

tools/memory-model: Make cmplitmushist.sh note timeouts
Currently, cmplitmushist.sh treats timeouts (as in the "--timeout"
argument) as "Missing Observation line". This can be misleading because
it is quite possible that running the test longer would have produced
a verification. This commit therefore changes cmplitmushist.sh to check
for timeouts and to report them with "Timed out".

tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"
The "--jobs" argument to the litmus-test scripts is similar to the "-jN"
argument to "make", so this commit allows the "-jN" form
tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"
The "--jobs" argument to the litmus-test scripts is similar to the "-jN"
argument to "make", so this commit allows the "-jN" form as well. While
in the area, it also prohibits the various forms of "-j0".
