VM opcodes only have <24-bit slot operands in the first word
* libguile/vm-engine.c (make-array): Change to only have
restricted-width operands in the first word. This instruction is
currently unused, however.
* module/system/vm/assembler.scm (assembler):
* module/system/vm/disassembler.scm (disassembler): Disallow
restricted-width operands in tail words.
