  61  * build a model of the JVM operand stack for the current method.
  62  *
  63  * The following checks are performed:
  64  *   - check for operand stack underflow (before each instruction)
  65  *   - check for operand stack overflow (after[1] each instruction)
  66  *   - check for matching stack depth at merging points
  67  *   - check for matching basic types[2] at merging points
  68  *   - check basic types for instruction input (except for BUILTIN*
  69  *         opcodes, INVOKE* opcodes and MULTIANEWARRAY)
  70  *
  71  * [1]) Checking this after the instruction should be ok. parse.c
  72  * counts the number of required stack slots in such a way that it is
  73  * only vital that we don't exceed `maxstack` at basic block
  74  * boundaries.
  75  *
  76  * [2]) 'basic types' means the distinction between INT, LONG, FLOAT,
  77  * DOUBLE and ADDRESS types. Subtypes of INT and different ADDRESS
  78  * types are not discerned.
