Robert O'Callahan effc52fedc Make `ID::` constants be `StaticIdString`s for better optimization. 
Their internal indexes will be known at compile time, like we already support for the `ID()` macro.

Jannis Harder d88d6fce87 kernel: Rewrite bufNormalize 
This is a complete rewrite of the RTLIL-kernel-side bufnorm code. This
is done to support inout ports and undirected connections as well as to
allow removal of cells while in bufnorm mode.

This doesn't yet update the (experimental) `bufnorm` pass, so to
manually test the new kernel functionality, it is important to only use
`bufnorm -update` and `bufnorm -reset` which rely entirely on the kernel
functionality. Other modes of the `bufnorm` pass may still fail in the
presence of inout ports or undirected connections.

Robert O'Callahan fee2b8992c Stop using `mutable` in `Const`. 
Now that we only call `bitvectorize()` in non-const methods, we can move the casting-away-const to only happen
in `bitvectorize()`, which is deprecated so only some plugins (maybe) are using it.

This means `const` `Const` methods don't change the underlying data, which means
they'll be safe to use from multiple threads if/when we want to do that.

Jannis Harder a97381448a Ensure static IdStrings get prepopulated when initializing yosys 
An alternative would be to call ensure_prepopulated() in various
IdString methods.

Jannis Harder 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.

Jannis Harder 2a4a9aedfe Ensure the ID macro consistently uses YOSYS_NAMESPACE_PREFIX 
The previous version of the ID macro used this for everything in the
Yosys namespace, so the new version should continue to do so.

Merge pull request #5248 from calewis/try_unordereded_map 
Use unordered_map instead of dict for IdString's char* to index storage.

Drew Lewis 2c8b4d7ad1 Use unordered_map instead of dict for IdString char* to index storage. 
dict is pretty slow when you don't ever need to iterate the container in
order.  And the hashfunction for char* in dict hashes for every single
byte in the string, likely doing significantly more work than std::hash.

Robert O'Callahan f25f8fe7c4 In the Verilog backend, only sort modules that we're going to emit. 
If you have a large design with a lot of modules and you use the Verilog
backend to emit modules one at a time to separate files, performance is
very low. The problem is that the Verilog backend calls `design->sort()`
every time, which sorts the contents of all modules, and this is slow
even when everything is already sorted.

We can easily fix this by only sorting the contents of modules that
we're actually going to emit.
