17183fff05 cmake: Enable -Wextra, and -Werror in some cases 
-Werror is not enabled by default, except on CI and for a few specific common traps, to avoid the inevitable breakages when new compiler versions add new diagnostics.

a30043c8da Fix assorted bugs in FPGA interchange. 
Fixes:
 - Only use map constant pins during routing, and not during placement.
 - Unmapped cell ports have no BEL pins.
 - Fix SiteRouter congestion not taking into account initial expansion.
 - Fix psuedo-site pip output.

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.
