Being a custom type means that it will be resolved *before* (e.g.) a wire can use it as a type.

Reduce comparisons of size_t and int
...
`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.

fmt: Allow non-constant $display calls in initial blocks
...
These are useful for formal verification with SBY where they can be used
to display solver chosen `rand const reg` signals and signals derived
from those.
The previous error message for non-constant initial $display statements
is downgraded to a log message. Constant initial $display statements
will be shown both during elaboration and become part of the RTLIL so
that the `sim` output is complete.

This makes tests/verilog/dynamic_range_lhs.v pass, after ensuring that
nowrshmsk is actually tested.
Stride is extracted from indexing of two-dimensional packed arrays and
variable slices on the form dst[i*stride +: width] = src, and is used
to optimize the generated CASE block.
Also uses less confusing variable names for indexing of lhs wires.
