* libguile/vm-engine.c: Change the RTL VM to number the procedure as
local 0, and other locals from 1. In the future we will want the FP
to point to local 0 instead of local 1. In the future also we can
elide the procedure for well-known closures (closures in which all
references are known call sites).
(make_closure, free_set): Instead of taking rest arguments, we add a
new free-set! op that initializes closures.
(free_ref): Take the closure as an argument.
* libguile/vm.c (rtl_boot_continuation_code): Remove comments, which
were out of date.
(rtl_apply_code, rtl_values_code): Update comments.
* module/system/vm/assembler.scm (intern-constant, emit-init-constants):
Adapt to locals numbering change.
(begin-kw-arity): For assert-nargs-ee purposes, nreq includes the
procedure.
* module/system/vm/disassembler.scm (code-annotation): Adapt annotation
for assert-nargs-ee/locals.
* test-suite/tests/rtl.test: Adapt tests.
* libguile/instructions.c (scm_rtl_instruction_list): Add an element to
the list to indicate that an instruction outputs to its first
argument.
* module/system/vm/assembler.scm:
* module/system/vm/disassembler.scm: Adapt.
