back.rtlil: avoid sync process emission in RTLIL. 
Avoiding emission of sync processes in RTLIL allows us to avoid a dependency on
matching the behavior expected by Yosys, which generally expects sync processes
in RTLIL to match those emitted by the output from its own Verilog parser.
This also simplifies the logic used in emitting RTLIL overall.

Combinatorial processes are still emitted however. Without these the RTLIL does
not have a high-level understanding of Switch statements, which significantly
diminishes the quality of emitted Verilog, as these are converted to `$mux`
cells in Yosys, which become `?` constructs when converted back to Verilog.

Fixes #603.
Fixes #672.

The `ports` argument has been passed implicitly, via `**kwargs`, and
that was broken during the deprecation.

Closes #659.

modwizcode 1ee2482c6b sim: represent time internally as 1ps units 
Using floats to represent simulation time internally isn't ideal
instead use 1ps internal units while continuing to use a floating
point based interface for compatibility.

Fixes #535.

whitequark ac13a5b3c9 sim._pyrtl: reject very large values. 
A check that rejects very large wires already exists in back.rtlil
because they cause performance and correctness issues with Verilog
tooling. Similar performance issues exist with the Python simulator.

This commit also adjusts back.rtlil to use the OverflowError
exception, same as in sim._pyrtl.

Fixes #588.
