Handle the abs() function in net context.
...
In net context we have to create a node that does the abs() function
for us. Elaborate that node and handle it all the way down to vvp.

Add signed bit based power to continuous assignments.
...
This patch adds the power operator for signed bit based values
in a continuous assignment. It also fixes a few other power
expression width problems. The expression width is still not
calculated correctly, since the correct method can produce huge
possible bit widths. The result is currently limited to the width
of the native long. This is because lround() is used to convert
from a double to an integer. A check in the code generator protects
the runtime from this limitation.
