coolrunner2: Separate and improve buffer cell insertion pass
The new pass will contain all of the logic for inserting "passthrough"
product term and XOR cells as appropriate for the architecture. For
example, this commit fixes connecting an input pin directly to another
output pin with no logic in between.

json: remove the 32-bit parameter special case
Before, the rules for encoding parameters in JSON were as follows:
- if the parameter is not a string:
- if it is exactly 32 bits long and there are no z or x bits, emit it
as an int
- otherwise, emit it as a string made of 0/1/x/z characters
- if the parameter is a string:
- if it contains only 0/1/x/z characters, append a space at the end
to distinguish it from a non-string
- otherwise, emit it directly
However, this caused a problem in the json11 parser used in nextpnr:
yosys emits unsigned ints, and nextpnr parses them as signed, using
the value of INT_MIN for values that overflow the signed int range.
This caused destruction of LUT5 initialization values. Since both
nextpnr and yosys parser can also accept 32-bit parameters in the
same encoding as other widths, let's just remove that special case.
The old behavior is still left behind a `-compat-int` flag, in case
someone relies on it.
