0a01963d07 VM hooks take no values
* libguile/vm-engine.c (RUN_HOOK0, RUN_HOOK1): Remove.
  (RUN_HOOK): Take hook name.
  (APPLY_HOOK, RETURN_HOOK, NEXT_HOOK, ABORT_CONTINUATION_HOOK): Use
  RUN_HOOK.
* libguile/vm.c (vm_dispatch_hook): Remove value count arg; hooks no
  longer receive values (e.g. the return hook now uses
  frame-return-values).
  (vm_dispatch_abort_hook): Remove value count, which was bogus because
  the active frame was the continuation which might contain other
  locals, potentially unboxed, not the implicit return-values frame.  In
  the future we could push on an implicit return-values frame instead.
* module/system/vm/traps.scm (trap-in-procedure, trap-frame-finish):
  (trap-in-dynamic-extent, trap-calls-to-procedure): Adapt abort hooks
  to not take values.  They weren't being used anyway!

  when a frame is at "return-values".
  (scm_init_frames_builtins): Register frame-return-values.
* libguile/vm-engine.c (RETURN_HOOK): Rename from POP_CONTINUATION_HOOK.
  (call, call-label): Remove PUSH_CONTINUATION_HOOK; it's unneeded, as
  you can always check the FP from an apply hook.
  (return-values): Run return hook before popping frame.
* libguile/vm.c (vm_dispatch_return_hook): Rename from
  vm_dispatch_pop_continuation_hook.  Remove push continuation hook.

b8a9a666f1 Rewrite subr implementation
* libguile/gsubr.c: Reimplement to store subr names and procedures in a
  side table, and to allocate fresh vcode for each subr.  This allows
  JIT of subrs, moves to a uniform all-code-starts-with-instrument-entry
  regime, and also allows statprof to distinguish between subrs based on
  IP.
* libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_NAME): Call out to functions,
  now that these are in a side table.
  (scm_subr_function, scm_subr_name): New exports.
  (scm_i_primitive_name): New internal function, for looking up a

  samples and call counts.

5c2e155fd7 Emit instrument-entry before programs
* module/system/vm/assembler.scm (<jit-data>, <meta>): Rework to have
  <meta> create the <jit-data> in the end-program, so that jit-data
  isn't mutable.  Record start and end PC values relative to '.rtl-text
  so that we don't need any more linker symbols.
  (emit-instrument-entry*, emit-instrument-loop*, begin-program):
  (end-program): Adapt.
  (begin-kw-arity): Include the initial instrument-entry in the first
  arity.

  routine.

  scm_op_instrument_entry, if any.

  (lower-cps): Adapt to add-loop-instrumentation name change.
* module/language/cps/loop-instrumentation.scm: Rename from
  handle-interrupts.scm and just add "instrument-loop" primcalls in

  appropriate.
