Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit.  This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.

This closes the implementation portion of SourceForge patch #100893.
