Robert O'Callahan d233581e16
Make `wire_load_tree_` default to unknown so we can detect when it's not present in a Liberty file. (#402) 
This is potentially a behavior change, but I think omitting this is rare. I've only seen it in some DTCD Liberty files.
In those Liberty libraries, it seems to be expected that the Liberty data is valid for all `WireloadTree` types.
Thus it is necessary to distinguish between "wire load tree was specified as 'balanced'" and "wire load tree
was not specified".

Add a less operator to BddPortVarMap (#258) 
bdd_port_var_map_, of type BddPortVarMap, is iterated over in
Power::evalBddActivity.  Previously the map used pointer comparison so
the iteration order was non-deterministic.  The computed density was
therefore non-deterministic due to the non-associativity of
floating-point addition.

[liberty] Fix use-before-free bug (#170) 
Before this change, findTableTemplate captured `name` always. This caused a segfault
when LibertyReader::beginTable calls it with `template_name`:

  const char *template_name = group->firstName();
  if (library_ && template_name) {
    tbl_template_ = library_->findTableTemplate(template_name, type);

This pointer is owned by the group and is freed when we hit sta::libertyGroupEnd.

Ensure that findTableTemplate does not capture `name` by using findKey.
