Marcin Kościelnicki b44d0e041f xilinx: use RAM32M/RAM64M for memories with two read ports 
This fixes inefficient LUT RAM usage for memories with one write
and two read ports (commonly used as register files).

Marcin Kościelnicki 00fba62711 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.

Improve ABC repository management in Makefile 
`rev-parse --short` output may have a different abbreviated hash length than
ABCREV, so a simple string comparison always fails, even if the correct
commit is checked out. Pass both commits through rev-parse and then
compare the full hashes instead.

Add an `echo-abc-rev` target so that packaging scripts can set ABCPULL=0 and
handle all the git nastiness themselves.
