2cb3b6e9b8 peepopt: add formal only peepopt to rewrite latches to ffs in clock gates 
* this is gated behind the -formalclk flag, which also disables the other
  synthesis focused optimizations

16ea497d7c pmgen: Have a single make pattern 
Remove duplicate %.pmg -> %_pm.h pattern. One of the duplicates overrode
the other, and in some conditions there were build races as to whether
the target directory for the generated header would exist. Instead have
a single rule which is properly generalized.

aa9b86aeec peepopt: Add left-shift 'shiftmul' variant 
Add a separate shiftmul pattern to match on left shifts which implement
demuxing. This mirrors the right shift pattern matcher but is probably
best kept separate instead of merging the two into a single matcher.
In any case the diff of the two matchers should be easily readable.

82f60ba938 Makefile: don't assume python is called python3 
On some architectures, notably on Windows, the official name for the
Python binary from python.org is `python`.  The build system assumes
that python is called `python3`, which breaks under this architecture.

There is already infrastructure in place to determine the name of the
Python binary when building PYOSYS.  Since Python is now always required
to build Yosys, enable this check universally which sets the
`PYTHON_EXECUTABLE` variable.

Then, reuse this variable in other Makefiles as necessary, rather than
hardcoding `python3` everywhere.
