Assigning a value to an enum signal that is not of the same type as the
enum requires an explicit cast.
To support this attach the type of a type cast to the resulting expression.
This allows the assignment elaboration to confirm that value has been
explicitly cast to the right type.
Also handle the case where the value is a constant. In this case create a
NetEConstEnum instead of a NetEConst as the resulting expression.

This patch fixes a bunch of objects to have the correct file/line
information. It also adds support for getting file/line information
for events (named events have a definition line).
When padding a signal or when creating a local signal the file and
line information should be related to where the new object was
created not the signal value it is being created from.
This patch modifies the NetE* pad_to_width() routines to take a
LineInfo object to set the location to the correct value.
It fixes some set_line() calls to use the correct location.
It fixes ports to not set the file/line information if it is
already defined. Doing this was causing the definition of
signals to become the instantiation instead of the real
module declaration.
This patch pads inputs and output ports correctly when the port
and the port expression have different widths. It does not fix
inout ports.
It also sets the file and line number information in the unsigned
pad_to_width() routine.
Factor common code for processing signed constants to be padded.
In the process, fix some minor bugs in the padding decisions.
