More array fixes and down indexed part selects can be a lval.
...
Here are some more array fixes. They are mostly better error messages
instead of just asserting and some code cleanup. The one new thing
that probably should have been a separate submission is that down
indexed part select [base -: width] can now be a lvalue.

Fix/enhance array part select code.
...
This patch fixes/enhances the array part select code. It also
verifies that any lval array index in a continuous assignment
is a constant value. Also, %set/av now uses index register 1 as
described in the documentation (as a bit offset).

Handle indexed part select in continuous assign.
...
Non-constant indexed part select in continuous assignment generates
a select node with the correct width. In the process factor out and
share some of the part select calculations with expr part select
handling methods.
