Robert O'Callahan e0ae7b7af4 Remove .c_str() calls from log()/log_error() 
There are some leftovers, but this is an easy regex-based approach that removes most of them.

register.h: Add internal_flag to Pass 
Update experimental pass warnings to use a shared function.  Reduces repetition, and also allows all of the warning flags to be combined (which at present is just experimental and the new internal).
Update `test_*` passes to call `internal()` in their constructors.

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
  $@))`.

Philippe Sauter 2f0f10cb87 peepopt: limit padding from shiftadd 
The input to a shift operation is padded.
This reduced the final number of MUX cells
but during techmap it can create huge
temporary multiplexers in the log shifter.
This significantly increases runtime and resources.

A limit is added with a warning when it is used.
