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.

Jannis Harder 0f13b55173 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.

Sean Luchen 4610889d27 Fix two parsing bugs that were causing private regression tests to fail. 
These were introduced by 0a6d9f4.
1) While in a paren "(", don't error on newline.
2) Don't parse an extra token when parsing vector ranges. Let the caller parse the next token as necessary.

Jannis Harder bc01468c75 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.

Jannis Harder 119e998f12 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.
