Add .cast/int and update .cast/real.
...
This patch adds .cast/int and updates .cast/real to act as a local
(temporary) net and to support either a signed or unsigned input.
The vvp_vector4_t class not can convert an arbitrarily sized double
to a vector value. This removes the restriction of lround().
Also document the new statements.

Make &A<> use the same thread access syntax as &PV<>.
...
This patch makes &A<> use the same thread access syntax as
&PV<> this is two unsigned numbers separated by a space
instead of a single number.

Add means for &A<> to index using a calculated index.
...
This is not a solution to all the problems, but is a better catch-all
then what is currently there. Allow the index field to be a T<> that
accesses the thread to get the address index.
Note that the lexor.lex currently returns the T<> as a T_SYMBOL, and the
users of T_SYMBOL objects need to interpret the meaning. This is
probably not the best idea, in light of all the other *<> formats that
now exist.

Remove documentation for memory opcodes.
...
The memory opcodes %assign/mv, %load/mv and %set/mv
were removed by a previous patch. This one removes
the documentation from opcodes.txt. It also removes
the documentation for the .mem* statements for the
same reason.

Add support for collapsed/aliased arrays.
...
Arrays of nets that have all their words collapsed together can become
a collapsed array as a whole. Add support for this case in the vvp code
generator and runtime.

lpm type is removed from the ivl_target API.
