octave-lyh: src/ov-usr-fcn.cc annotate

annotate src/ov-usr-fcn.cc @ 12920:5d18231eee00

Extend profiling support to operators. * profiler.h: Always use std::string with profiler name instead of octave_function references for identifying functions. * profiler.cc: Adapt for that. * ov-builtin.cc: Ditto. * ov-mex-fcn.cc: Ditto. * ov-usr-fcn.cc: Ditto. * pt-binop.cc (tree_binary_expression::rvalue1): Collect profiler data. * pt-unop.cc (tree_prefix_expression::rvalue1): Ditto. (tree_postfix_expression::rvalue1): Ditto.
