Better formatting of Cr<> label for real valued drivers.
...
Rework the encoding of a real value in the Cr<> label to be similar to
the format used by the %loadi/wr instruction. This mantissa-expoment
format better carries all the bits of the desired real value with
plenty of fidelity and range.

Add real comparisons in continuous assignments.

This patch adds real comparisons in continuous assignments.
It also converts bit based constants to real values when needed
by the comparisons.

Add %load/avp0 opcode and fix %load/vp0.
...
This patch adds a new opcode %load/avp0 that is used to load a
word from an array and add a value to it. %load/vp0 was
changed/fixed to do the summation at the result width not the
vector width. This allows small vectors to index large arrays with
an offset. A few errors in the opcodes.txt file were also fixed.

Add %ix/getv instruction

The %ix/getv instruction loads an integer register directly from
a signal vector. This is an optimization that an index register
is loaded from an expression is only a signal. It avoids the thread

Make the modpath source define the VPI modpath object.
...
The modpath source node defines the modpath object, and carries the
nodes for the source expression. The modpath outputs are references
by pointers to the vpiModPath that is not in itself a vpi object
any more. This makes the VPI view of a module path look like the
source-destinaiton pair that is the IEEE1364 description of the
modpath.

inapropriate vpi_signal.cc source file.
