* libguile/objcodes.c (make_objcode_by_mmap, scm_c_make_objcode_slice):
Verify the lengths with the meta-length.
(scm_objcode_meta): New procedure, for getting at the meta-info of an
objcode.
(scm_objcode_to_bytecode):
(scm_write_objcode): Write bytecode with the metadata too.
* module/system/vm/objcode.scm: Export object-meta.
* module/language/assembly.scm (byte-length):
* module/language/assembly/compile-bytecode.scm (write-bytecode):
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/disassemble.scm (disassemble-load-program):
* module/language/glil/compile-assembly.scm (glil->assembly):
* test-suite/tests/asm-to-bytecode.test ("compiler"): Change to
load-program format to have meta-or-#f instead of meta-length, so that
we can serialize the meta as objcode without a load-program byte. Add a
test for writing out the meta.
