Fix for pr3582052.
...
The code that calculated the canonical index for a multi-dimensional
array access did not correctly estimate the index expression width
in the case that the first index value was a constant zero. This
patch fixes the problem, and, in passing, also makes the expression
calculation more efficient if any of the indices are constant zeroes.

Support for dynamic arrays of strings.
...
Strings, when put into dynamic arrays, are treated as first class
types much line reals. Add the code generator and vvp support for
this situation. Also fix a bug distinguishing between character
selects from strings and select form arrays of strings.

This patch updates the vvp code so it will compile with the valgrind hooks
again. There are still new constructs that need to be cleaned up correctly
and some old constructs were changed enough that the old code no longer
works, but the rest of this can be done as an incremental improvement.
