86d82dff58 systemc: Keep all pre-init processes on a single list.
We were keeping track of processes which should be initialized and
those which shouldn't on two different lists, and then processing
each list one after the other. This could reorder processes from the
order they were created, and so cause spurious differences which cause
the Accellera tests to fail.

This does make the scheduler slightly simpler, so it's not all bad.

18ca156d81 systemc: Change how sc_clock creates processes to match the tests.
Accellera sets up the mechanism which toggles sc_clock differently
than it's set up in gem5. This change moves things around a little to
more closely match the order things are done by Accellera so that the
test output matches.

1cc084fc7a systemc: Raise an error when SC_METHOD, etc. is used after starting.
Those mechanisms for creating processes are only allowed before the
end of elaboration, or in other words before sc_start is called.
Technically the check in Accellera's implementation won't trigger if
the simulation is stopped, and we immitate that behavior.

a18e901b16 systemc: Add some deprecated features to sc_clock.*.
Add in two deprecated typedefs, and a deprecated constructor. These
are necessary to get the regressions to build.
