0d8e5d965f Sign extend port connections where necessary 
- Signed cell outputs are sign extended when bound to larger wires
- Signed connections are sign extended when bound to larger cell inputs
- Sign extension is performed in hierarchy and flatten phases
- genrtlil indirects signed constants through signed wires
- Other phases producing RTLIL may need to be updated to preserve
  signedness information
- Resolves #1418
- Resolves #2265

c7ceed3fd3 Simple support for %l format specifier 
Yosys doesn't support libraries, so this provides the same behavior as
%m, as some other tools have opted to do.
