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.

celledges: Use b_width_capped for left shifts 
`b_width_capped` already exists for preventing arithmetic overflow, limiting the value of `b_width` to 30.  This just changes the left shifts to also use it.
The caveat of incorrect results for extremely large values of `a_width` still applies, as does the improbability of that actually happening.
This fixes #4844 (or at least, the floating point exception; the circuit still isn't valid but I think that's fine).

David Sawatzke 09ead2daa9 tcl: Update help message to clarify usage of result.string 
In the current documentation, it's unclear if `result.string` serves as
an example of a string name. It is furthermore unclear what the purpose
of `result.string` is. Clarify this by adding a small explanation (and
fix a typo)

macc: Stop using the B port

Martin Povišer 652a1b9806 macc: Stop using the B port 
The B port is for single-bit summands. These can just as well be
represented as an additional summand on the A port (which supports
summands of arbitrary width). An upcoming `$macc_v2` cell won't be
special-casing single-bit summands in any way.

In preparation, make the following changes:

 * remove the `bit_ports` field from the `Macc` helper (instead add any
   single-bit summands to `ports` next to other summands)

 * leave `B` empty on cells emitted from `Macc::to_cell`
