f9bd692f75 Change how package pin IO sites are selected. 
The first site type that matches is now selected, under the premise that
the early site types are more general.

c385321248 Add initial site router. 
This site router likely cannot handle the full problem space.  It may
need to be replaced with a more generalize approach as testing
continues.

e189666a2d Add a Bits utility library. 
This library captures use of __builtin_popcount and __builtin_ctz on
GCC/clang and hopefully handles the MSVC case.

bb4fa7af5b [FPGA Interchange] Add Cell -> BEL Pin maps. 
This also expands the FPGA interchange Arch BBA to include placement
constraints, but doesn't implement them yet.

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.

non-Tcl users this, "[<number>]" just return themselves.
