Creating a case sensitive transfer vector on VAX is a nusiance, so for
now (unless someone asks for it) we only do UPPERCASE on VAX.  This required
a couple changes to the way MAKE_SYMBOL_VECTOR.TES works.
Correctly formatted version of the VAX transfer vector.
More changes to properly generate a VAX transfer vector.  However, we need
more changes to support case-sensitivity on Alpha/I64, whie no caring on
VAX.
