Zachary Snow fb604109bf don't sign-extend signed unsized numbers with a leading 1 bit 
I'm opting for iverilog's interpretation of the specifications here. The
commercial simulators I tested seem to agree.

Zachary Snow 2aff725ea2 drop tf block edge case 
- The deleted chunk in TFBlock has been unreachable since 57ef23ef. The
  RemoveComments change would make it reachable by dropping the leading
  Null in a task or function body.
- The optimization in TFBlock was unsound because the nested block could
  shadow identifiers used (but not defined) in the tail of the outer
  block.
- The optimization is not clearly necessary, so I'm dropping it for now.
- Expand tf_block test coverage.
