cosmoV_execute by about 20% from benchmarking. of course, if you know
your compiler supports computed gotos, you can define VM_JUMPTABLE
although, this is disabled when VM_DEBUG is defined, since it can cause
issues with debugging
BTW: be weary of maliciously crafted cosmo dumps!! it's very easy to crash
cosmo with this enabled and reading invalid opcodes due to us just using the
opcode as an index into the jump table
