pmgen: Move passes out of pmgen folder
...
- Techlib pmgens are now in relevant techlibs/*.
- `peepopt` pmgens are now in passes/opt.
- `test_pmgen` is still in passes/pmgen.
- Update `Makefile.inc` and `.gitignore` file(s) to match new `*_pm.h` location,
as well as the `#include`s.
- Change default `%_pm.h` make target to `techlibs/%_pm.h` and move it to the
top level Makefile.
- Update pmgen target to use `$(notdir $*)` (where `$*` is the part of the file
name that matched the '%' in the target) instead of `$(subst _pm.h,,$(notdir
$@))`.

memory_share: Split off feedback path finding as a separate pass.
...
memory_share is actually three passes in a trenchcoat. Split off the
one that has the least in common with the other two as a separate pass.

Implement opt_share
...
This pass identifies arithmetic operators that share an operand and whose
results are used in mutually exclusive cases controlled by a multiplexer, and
merges them together by multiplexing the other operands

Initial version of opt_demorgan is functioning for AND/OR gates. Not the prettiest results for bus inputs, but this can be improved
