fde622e050 * generate a loadvmtaddrnode wrapper around Java objectdef typenode arguments
to tasnode (like for regular Object Pascal classes)
  * don't collect WPO information for Java classes in tloadvmtaddrnode.pass_1()
    (devirtualization can't work for Java, since classes can always be loaded
     at run time, except for final/sealed classes -- but that's not yet
     implemented)
  + JVM is-node support, unified JVM type checking codegen for is- and as-nodes

ee8b662fa1 + dynamic array support for the JVM target: setlength(), length(), high():
o since the JVM does not support call-by-reference, setlength() works
     by taking an argument pointing to the old array and one to the new
     array (the latter is always created in advance on the caller side,
     even if not strictly required, because we cannot easily create it
     on the callee side in an efficient way). Then we copy parts of the
     old array to the new array as necessary
   o to represent creating a new dynamic array, the JVM target uses
     an in_new_x tinlinenode
  + tasnode support for the JVM. Special: it can also be used to convert
    java.lang.Object to dynamic arrays, and dynamic arrays of java.lang.Object
    to dynamic arrays with more dimensions (arrays are special JVM objects,
    and such support is required for the setlength support)
  + check whether explicit type conversions are valid, and if so, add the
    necessary conversion code since we cannot simply reinterpret bit patterns
    in most cases in the JVM:
   o in case of class and/or dynamic array types, convert to an as-node
   o in case of int-to-float or float-to-int, use java.lang.Float/Double
     helpers (+ added the definitions of these helpers to the system unit)
