gdb/sim: Assert that the simulator ptid is not null_ptid
We assign the simulator inferior a fake ptid. If this ptid is ever
set to null_ptid then we are going to run into problems - the
simulator ptid is what we return from gdbsim_target::wait, and this in
turn is used to look up the inferior data with a call to
find_inferior_pid, which asserts the pid is not 0 (which it is in
null_pid).
This commit adds an assert that the simulator's fake pid is not
null_ptid. There should be no user visible changes after this commit.
gdb/ChangeLog:
* remote-sim.c (sim_inferior_data::sim_inferior_data): Assert that
we don't set the fake simulator ptid to the null_ptid.
