...
Replace `cutpoint -blackbox` behaviour with `cutpoint -blackbox -instances` behaviour.
Drop `-instances` flag.
Add `-noscopeinfo` flag.
Use `RTLIL::Selection::boxed_module()` helper to shortcut blackbox check.
Update `cutpoint_blackbox.ys` tests to match.

design.cc: Fix selections when copying

Use `Design::selected_modules()` directly, popping at the end instead of copying the selection.
Also default to a complete selection so that boxes work as before.
Simplify to using `RTLIL::SELECT_WHOLE_CMDERR` instead of doing it manually.
Also add tests for importing selections with boxes.

opt_expr: Fix #4590
...
If all the (non-select) inputs of a `$_MUX{4,8,16}_` are undefined, replace it, just like we do for `$mux` and `$_MUX_`.
Add `tests/opt/opt_expr_mux_undef.ys` to verify this.
This doesn't do any const folding on the wide muxes, or shrinking to less wide muxes. It only handles the case where all inputs are 'x and the mux can be completely removed.

Liberty file caching with new libcache command
...
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.

read_liberty: Faster std::string construction in the liberty lexer
...
This extends the `LibertyInputStream` added in the previous commit to
allow arbitrary lookahead. Then this uses the lookahead to find the
total length of the token within the input buffer, instead of consuming
the token byte by byte while appending to a std::string. Constructing
the std::string with the total length is known avoids any reallocations
from growing std::string's buffer.

read_liberty: Faster input handling for the liberty lexer
...
The lexer for liberty files was using istream's `get` and `unget` which
are notorious for bad performance and that showed up during profiling.
This replaces the direct `istream` use with a custom LibertyInputStream
that does its own buffering to provide `get` and `unget` that behave the
same way but are implemented with a fast path that is easy to inline and
optimize.
