guile/libguile/jit.c
Andy Wingo 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
  primitive name based on IP.
  (scm_apply_subr): Take the subr index.
* libguile/vm-engine.c (subr-call):
* libguile/jit.c (compile_subr_call): Adapt to take index as arg.
* module/statprof.scm (sample-stack-procs, count-call):
  (stack-samples->procedure-data): Update to always record IP in stack
  samples and call counts.
* module/system/vm/frame.scm (frame-procedure-name): Simplify.
  (frame-instruction-pointer-or-primitive-procedure-name): Removed.
* libguile/programs.h:
* libguile/programs.c (scm_primitive_code_name): New function.
* module/system/vm/program.scm (primitive-code-name): New export.
