sim: cr16/d10v: restore generated headers dep

While cleaning up stale make rules, one too many were deleted. The
build system autogenerates static rules, but not generated files.

common: cgen-mem/cgen-ops: fix extern inline handling

With newer versions of gcc (5.x), the extern inline we're using with the
cgen-{mem,ops} modules no longer work. Since this code really wants the
gnu inline semantics, use that attribute explicitly.

sim: arm: convert to nrun

A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.

sim: arm: delete NEED_UI_LOOP_HOOK handling

sim: arm: clean up misc warnings

Also delete a few unused funcs.

sim: arm: use common configure options

In preparation for converting to nrun, call the common functions that
are needed. This doesn't produce any new warnings, and the generated
code should be the same.
