d34ac0c87d Make log() use the FmtString infrastructure. 
Now `log()` supports `std::string`.

We have to fix a few places where the format parameter was not a compile time constant.
This is mostly trivial.

61a00b9131 memory_libmap: Fix use of uninitialized value for async read ports 
The code in memory_libmap expects `clk_en` to be initialized for all
`PortVariant`s but the parsing in memlib.cc didn't initialize it for
variants of kind `PortKind::Ar` (async read ports).

While this fixes the immediate CI failure, it would be best to refactor
the code so it becomes obvious if something isn't initialized.

b6db32873d Add IdString const &id_string() const to StaticIdString and IdString 
The vast majority of ID(...) uses are in a context that is overloaded
for StaticIdString or will cause implicit conversion to an IdString
constant reference. For some sufficently overloaded contexts, implicit
conversion may fail, so it's useful to have a method to force obtaining
a `IdString const &` from an ID(...) use.

When turning all literal IdStrings of the codebase into StaticIdStrings
this was needed in exactly one place, for which this commit adds an
`id_string()` call.

238e437fca proc_dff: refactor inference logic 
* Instead of an ad hoc mix of optimizations and inferences, this tries
  to make it more principled by first extracting a set of asynchronous
  update rules from the process, then optimizing them before lowering
  them to a concrete flip-flop type, preferring simpler ones

ae8c4e2ea6 libparse/filterlib: mark LibertyParser::error() as weak 
When FILTERLIB is defined (attempts to compile libparse more or less standalone,) mark the `LibertyParser::error()` as weak so utilities using libparse as a library can override its behavior (the default behavior being exit(1)). As the code is quite performance-critical, I've elected to not modify it to raise an exception or have a callback or similar and simply allow for a link-time replacement.

8c04e5266c Use commutative hashing instead of expensive allocation and sorting 
For one of our large circuits, this improves the `OptMergePass` runtime
from about 150s to about 130s. It's also simpler code.

3f2c4f6f83 Remove redundant construction of assign_map. 
We call 'assign_map.set()' below which wipes the `SigMap` and reconstructs it.

This operation is expensive because it scans the whole module. I think it's
better to make heavyweight operations more visible so I'm removing
the less obvious operation.

ac8259b02e Preserve assign_map across ABC invocations. 
Currently `assign_map` is rebuilt from the module from scratch every time we invoke ABC.
That doesn't scale when we do thousands of ABC runs over large modules. Instead,
create it once and then maintain incrementally it as we update the module.
