Force abc to align memory to 8 bytes

Apparently abc has a memory pool implementation that by default returns
memory that is unaligned. There is a workaround in the abc makefile that
uses uname to look for "arm" specifically and then sets the alignment.
However, ARM is not the only platform that requires proper alignment
(e.g. emscripten does too). For now, pessimistically force the alignment
for 8 bytes all the time (somehow 4 wasn't enough for fixing emscripten
despite being approximately a 32-bit platform).

coolrunner2: Improve optimization for TFF/counters

coolrunner2: Add an ANDTERM/XOR between chained FFs

In some cases (e.g. the low bits of counters) the design might end up
with a flip-flop whose input is directly driven by another flip-flop.
This isn't possible in the Coolrunner-II architecture, so add a single
AND term and XOR in this case.
