797eee4264 sim: sim-stop/sim-reason/sim-reg: move to common obj list
Now that all arches (for the most part) have moved over, move sim-stop.o,
sim-reason.o, and sim-reg.o to the common object list and out of all the
arch ports.

6e4f085c7f sim: sim-close: unify sim_close logic
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did.  Now we have a single module that takes care of
all the logic for us.

Most of the non-cgen based ones could be deleted outright.  The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.

We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.

fa8f87e53b sim: trace: add a basic cpu register class
The bfin/msp430 ports already had trace logic set up for reading/writing
cpu registers, albeit using different unrelated levels (core & vpu).  Add
a proper register class for these and for other ports.

7d5c6c43ca sim: syscall: add common sim_syscall helpers
Many ports have the same sim syscall logic, so add some helpers to handle
all the common details.  The arches still have to deal with the unpacking
and packing of the syscall arguments, but the rest of the sim<->callback
glue is now shared.

61a0c964e6 sim: syscall: unify memory helpers

a348708291 sim: drop -DTRACE from configure

helper.  Punt it from configure.

5b064994f0 sim: msp430: use new common trace print helpers
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx".
The output is the same, but the code is nicer to read.

c1d8560ea5 sim: msp430: delete unused trace macros
These macros were copied from the Blackfin port but never used, so delete
them as part of the trace unification work.

20bca71d82 sim: unify SIM_CPU definition
Since every target typedefs this the same way, move it to the common code.

We have to leave Blackfin behind here for now because of inter-dependencies
on types and headers: sim-base.h includes sim-model.h which needs types in
machs.h which needs types in bfim-sim.h which needs SIM_CPU.

7e83aa92f2 sim: unify sim_cia definition
Almost every target defines sim_cia the same way -- either using the
address_word type directly, or a type of equivalent size.  The only
odd one out is sh64 (who has 32bit address_word and 64bit cia), and
even that case doesn't seem to make sense.  We'll put off clean up
though of sh64 and at least set up a sensible default for everyone.

034685f9ce sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET}
except the latter adds a layer of indirection via the sim state.  This
lets models set up different functions at runtime and doesn't reach so
directly into the arch-specific cpu state.

It also doesn't make sense to have two sets of macros that do exactly
the same thing, so lets standardize on the one that gets us more.

78e9aa70fe sim: unify sim-cpu usage
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.

ae7d0cac8c sim: rename tconfig.in to tconfig.h
Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h.  Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.

It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.

This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.

465fb143c8 sim: make nrun the default run program
We want people to stop using the run.c frontend, but it's hard to notice
when it's still set as the default.  Lets flip things so nrun.c is the
default, and users of run.c will get an error by default.  We turn that
error into a warning for existing sims so we don't break them -- this is
mostly meant for people starting new ports.
