Charles G. Waldman <cgw@fnal.gov>: 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.
