Fix inner and outer stack cuts to match on procedure code
* doc/ref/api-debug.texi (Stack Capture): Update make-stack docs.
* libguile/programs.h:
* libguile/programs.c (scm_program_address_range): New internal
procedure.
* libguile/stacks.c (narrow_stack): Interpret a pair of integers as an
address range. If a cut is a procedure, attempt to resolve it to an
address range.
(scm_make_stack): Update docstring.
* module/system/vm/program.scm (program-address-range): New exported
procedure.
* module/statprof.scm (statprof, gcprof): Use program-address-range to
get the outer-cut, for efficiency.
