before this change, we define the CMAKE_CXX_FLAGS_${CONFIG} directly.
and some of the configurations are supposed to generate debugging info with
"-g -gz" options, but they failed to include these options in the cxx
flags.
in this change:
* a macro named `update_cxx_flags` is introduced to set this option.
* this macro also sets -O option
instead of using function, this facility is implemented as a macro so
that we can update the CMAKE_CXX_FLAGS_${CONFIG} without setting
this variable with awkward syntax like set
```cmake
set(${flags} "${${flags}}" PARENT_SCOPE)
```
this mirrors the behavior in configure.py in sense that the latter
sets the option on a per-mode basis, and interprets the option to
compiling option.
