[Olena-patches] 675: Add a morpher to count read-write ops.

2006-10-24 Thierry GERAUD &lt;theo(a)tegucigalpa.lrde.epita.fr&gt; Add a morpher to count read-write ops. * tests/morphers/count_rw_morpher.cc: New. * tests/morphers/Makefile.am: Update. * oln/morpher/count_rw.hh: New. * oln/value/proxy.hh: New. * oln/value/rw_counter.hh: New. * oln/Makefile.am: Update. * oln/core/traits_id.hh (unop_vproxy, binop_vproxy): New. (others): Update. * oln/core/typedefs.hh (oln_is_computed, oln_is_computed_): New. * oln/morpher/internal/image_value_morpher.hh (image_value_morpher): New overloading for ctor. (image_): Add & to its type.
