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.
