v0.0.0-6162-ga6510014e

Improve verification performance by using a std:vector<bool> bitset

to keep track of seen ids, rather than an absl::flat_hash_set<Node*>.

40% relative improvement in time taken by VerifyNodeIdUnique for one workload
(2% of CPU time total down to 1.2%).

v0.0.0-6155-g33fe90674

Add channel matcher for proc-scoped channels.

This required removing an unused id matcher as channel references don't have ids. One kind of matching no longer works because C++: `send(m::Add(), channel)` where `channel` is `Channel*`.

As seen in CI run
https://github.com/google/xls/actions/runs/11335606242/job/31524066818#step:6:29

No need to generate warnings in code that are not directly actionable.

v0.0.0-6094-g22968c012

Looks like previously used helper functions, but not in use
anymore.

Found by clang-tidy [clang-diagnostic-unused-function] check,
and also are warned about while compiling.

v0.0.0-6078-ge6932ecc5

Fix dangling help message.

An ephemeral string in a flag help message ends up being assigned
to a string_view which holds the reference to that temporary.

Instead, keep the generated help message backed by storage, so that
it can be safely passed to a string_view.

Fix typo in butterfly topology documentation.

Change "-tree" to "-fly" when needed and change "-" to "\-" to correctly render the italics.

v0.0.0-6045-gd0c9bbd4d

Make codegen implement shra as a function.

This allows us to bind the intermediate result `$signed(to_shift) >>> amount` to a reg with a defined width, which avoids the `$signed()` having a self-determined width, which is a lint finding.

Fixes google/xls#1642.
