Martin Povišer 80b8cd19c4 rtlil: Fix value type for iterator over `SigSpec` 
When we are iterating over a `SigSpec`, the visited values will be of
type `SigBit` (as is the return type of `operator*()`). Account for that
in the publicly declared types.

Martin Povišer 189064b8da rtlil, hashlib: Remove deprecated `std::iterator` usage 
`std::iterator` has been deprecated in C++17. Yosys is being compiled
against the C++11 standard but plugins can opt to compile against a
newer one. To silence some deprecation warnings when those plugins are
being compiled, replace the `std::iterator` inheritance with the
equivalent type declarations.

Martin Povišer 44c72e5223 python: Fix import in plugin example 
When a plugin is being loaded from Python source, the binding will be
available under

    import libyosys

That is unfortunately different from how a self-standing Python program
would import the Yosys interface, which is

    from pyosys import libyosys

Until that is made consistent, at least fix the example to have it
working as is.

Jannis Harder 7b74caa5db peepopt: Fix padding for the peepopt_shiftmul_right pattern 
The previous version could easily generate a large amount of padding
when the constant factor was significantly larger than the width of the
shift data input. This could lead to huge amounts of logic being
generated before then being optimized away at a huge performance and
memory cost.

Additionally and more critically, when the input width was not a
multiple of the constant factor, the input data was padded with 'x bits
to such a multiple before interspersing the 'x padding needed to align
the selectable windows to power-of-two offsets.

Such a final padding would not be correct for shifts besides $shiftx,
and the previous version did attempt to remove that final padding at the
end so that the native zero/sign/x-extension behavior of the shift cell
would be used, but since the last selectable window also got
power-of-two padding appended after the padding the code is trying to
remove got added, it did not actually fully remove it in some cases.

I changed the code to only add 'x padding between selectable windows,
leaving the last selectable window unpadded. This omits the need to add
final padding to a multiple of the constant factor in the first place.
In turn, that means the only 'x bits added are actually impossible to
select. As a side effect no padding is added when the constant factor is
equal to or larger than the width of the shift data input, also solving
the reported performance bug.

This fixes #4056

Martin Povišer 16ea497d7c pmgen: Have a single make pattern 
Remove duplicate %.pmg -> %_pm.h pattern. One of the duplicates overrode
the other, and in some conditions there were build races as to whether
the target directory for the generated header would exist. Instead have
a single rule which is properly generalized.

Krystine Sherwin 497cd021af QLF_TDP36K: truncation tests matter 
Expected values are now stored in full precision rather than truncating to the same value as the input.
i.e. 0x5a5a5a5a will truncate to 0x5a5a for write data but will remain 0x5a5a5a5a for expected read.
