Implement automatic detection of CPU topology on Windows
The CPU topology is now automatically detected on Windows
systems with less than 33 logical processors. The runtime system
will now, also on Windows, by default bind schedulers to logical
processors using the 'default_bind' bind type if the amount of
schedulers is at least equal to the amount of logical processors
configured, binding of schedulers is supported, and a CPU topology
is available at startup.
