type2str returns a string that doesn't start with $ or \, so it can't be

opt_expr: Fix mul/div/mod by POT patterns to support >= 32 bits.
...
The previous code, in addition to being needlessly limitted to 32 bits
in the first place, also had UB for the 31th bit (doing 1 << 31).

opt_expr: Optimize div/mod by const 1.
...
Turns out the code for div by a power of 2 is already almost capable of
optimizing this to a shift-by-0 or and-with-0, which will be further
folded into nothingness; let's beef it up to handle div by 1 as well.
Fixes #2820 .

verilog: check for module scope identifiers during width detection
...
The recent fix for case expression width detection causes the width of
the expressions to be queried before they are simplified. Because the
logic supporting module scope identifiers only existed in simplify,
looking them up would fail during width detection. This moves the logic
to a common helper used in both simplify() and detectSignWidthWorker().

kernel/mem: Recognize some deprecated memory port configs.
...
Transparency is meaningless for asynchronous ports, so we assume
transparent == false to simplify the code in this case. Likewise,
enable is meaningless, and we assume it is const-1. However,
turns out that nMigen emits the former, and Verilog frontend emits
the latter, so squash these issues when ingesting a $memrd cell.

This essentially adds wide port support for free in passes that don't
have a usefully better way of handling wide ports than just breaking
them up to narrow ports, avoiding "please run memory_narrow" annoyance.

mem/extract_rdff: Fix "no FF made" edge case.
...
When converting a sync transparent read port with const address to async
read port, nothing at all needs to be done other than clk_enable change,
and thus we have no FF cell to return. Handle this case correctly in
the helper and in its users.

mem/extract_rdff: Add alternate transparency handling.
...
When extracting read register from a transparent port that has an
enable, reset, or initial value, the usual trick of putting a register
on the address instead of data doesn't work. In this case, create soft
transparency logic instead.
When transparency masks land, this will also be used to handle ports
that are transparent to only a subset of write ports.

kernel/mem: Add model support for read port init value and resets.
...
Like wide port support, this is still completely unusable, and support
in various passes will be gradually added later. It also has no support
at all in the cell library, so attempting to create a read port with
a reset or initial value will cause an assert failure for now.
