Don't delete L-value concat signals and give a better error message. 

This patch removes the code that was deleting the signals in an L-value
concat if the concatenation failed to elaborate. This is incorrect since
the signal could be used in another context that is processed later. The
error message when an output/inout port fails to elaborate was also
improved to give the expression that is connected to the port.
