Added basic CPU topology information to cpuid code

We can now detect the locality of hardware threads, cores,
and packages for Intel and AMD CPUs under Linux and Windows.
In particular, this provides an array with locality order
for logical processors that can be used to optimize placement.
Refs #1086, #1101.
