First experimental profiler implementation with flat profile.
* profiler.cc: New file.
* profiler.h: New file.
* Makefile.am: Include new files in build process.
* oct-parse.yy (frob_function): Store location of function parsed.
* ov-fcn.h (octave_function::profiler_name): New method.
* ov-builtin.cc (octave_builtin::do_multi_index_op): Record timings in profiler.
* ov-mex-fcn.cc (octave_mex_function::do_multi_index_op): Ditto.
* ov-usr-fcn.cc (octave_user_script::do_multi_index_op): Ditto.
(octave_user_function::do_multi_index_op): Ditto.
(octave_user_function::octave_user_function): Initialize location_line/column.
(octave_user_function::profiler_name): New method.
* ov-usr-fcn.h (octave_user_function): New variables location_line,
location column and new method stash_fcn_location to set them.
* pt-fcn-handle.cc (tree_anon_fcn_handle::rvalue1): Store location.
