Andy Wingo 6f78702819 add new language between assembly and objcode: bytecode
* module/language/bytecode/Makefile.am:
* module/language/bytecode/spec.scm: Add another language to the stack,
  bytecode. Bytecode is the u8vector form of object code..

* configure.in:
* module/language/Makefile.am:
* module/language/assembly/Makefile.am:
* test-suite/tests/asm-to-bytecode.test:
* module/language/assembly/spec.scm:
* module/language/assembly/compile-bytecode.scm: Update to include the
  new pass.
