Fix assert() segfaults with profiler (bug #39587, bug #39586).
* profiler.cc (profile_data_accumulator::tree_node::exit,
profile_data_accumulator::exit_function, ): Comment
out assert() statements which are not valid when profile is called
from within a function.
* profiler.cc (F__profiler_reset__, F__profiler_data__,
F__profiler_enable__): Use correct function name in Texinfo
docstring.
* profiler.cc (F__profiler_data__): define retval(1) first to
resize return vector just once.
