Because exit_threads() references the global object TM, we
need to call the function when still inside main(), otherwise,
due to undefined global object initialization and destruction
we could end up with referencing an already destroyed object.
Actually this should not happen because Application singleton
is initialized _only_ after all the other globals due to how
Application::initialize() is defined, but this is very tricky
C++ and not easy to follow, even for me ;-)
Also rearranged a bit main() code flow.
No functional change.

Patch from Joona with extension to benchmark and inclusion
of Depth(0) moves generation by me.
Note that to test also qsearch and in particulary checks
generations a change in the end condition is needed.

Add a new argument to bench to specify the name of the
file where timing information will be saved for each
benchmark session.
This argument is optional, if not specified file will
not be created.

With this patch at the applications startup a line is printed
with info about use of optimized 64 bit routines and hardware
POPCNT.
Also allow the possibility to disable POPCNT support during
PGO compiles to exercise the fallback software only path.

Centralize in a single object all the global resources
management and avoid a bunch of sparse exit() calls.
This is more reliable and clean and more stick to C++ coding
practices.

Now I/O is fully done with C++ iostreams.
The only exception is in non-windows version
of Bioskey() in misc.cpp
