This library captures use of __builtin_popcount and __builtin_ctz on
GCC/clang and hopefully handles the MSVC case.

c7c13cd95f Remove isValidBelForCell 
This Arch API dates from when we were first working out how to
implement placement validity checking, and in practice is little used by
the core parts of placer1/HeAP and the Arch implementation involves a
lot of duplication with isBelLocationValid.

In the short term; placement validity checking is better served by the
combination of checkBelAvail and isValidBelForCellType before placement;
followed by isBelLocationValid after placement (potentially after
moving/swapping multiple cells).

Longer term, removing this API makes things a bit cleaner for a new
validity checking API.
