7922b3bfc4 Replace DelayInfo with DelayPair/DelayQuad 
This replaces the arch-specific DelayInfo structure with new DelayPair
(min/max only) and DelayQuad (min/max for both rise and fall) structures
that form part of common code.

This further reduces the amount of arch-specific code; and also provides
useful data structures for timing analysis which will need to delay
with pairs/quads of delays as it is improved.

While there may be a small performance cost to arches that didn't
separate the rise/fall cases (arches that aren't currently separating
the min/max cases just need to be fixed...) in DelayInfo, my expectation
is that inlining will mean this doesn't make much difference.

535723f414 Start making use of getBelPinsForCellPin API 
This replaces getNetinfoSinkWire with 3 new functions for different use
cases.

At the moment all existing code has been moved to getNetinfoSinkWire
with phys_idx=0 so the build doesn't break; but this won't yet function
properly with more than one sink. But it provides a base on which to
work on refactoring the routers to support this case.

Add option to print critical path source code 
In order to make debugging the critical path easier, add an option that
will log the location each net was defined, if known.
If the file that contains the definition is known, and is readable, also
print the part of the source HDL responsible for the signal definition.
