[PATCH][_GLIBCXX_DEBUG] Fix safe.base.h comments

[François Dumont]

I initially planned to commit this directly as trivial but as I'm not a 
Doxygen expert, maybe there is something better to do.

Without any feedback I plan to commit in a couple of days.

     libstdc++: [_GLIBCXX_DEBUG] Fix safe.base.h comments


     'Likewise' was used to start the documentation of some methods. 
This is bad
     practice because in one case the method had been moved and so was 
not anymore
     next to the other method this 'likewise' was referring to. And more 
generally,
     when documentation is consulted through the Doxygen generated 
files, the
     'Likewise' is then not referring to any meaningful context.

     'Likewise' is replaced by 'Like <method-name>'.

     libstdc++-v3/ChangeLog:

             * include/debug/safe_base.h
             (_Safe_iterator_base::_M_attach_single): Adapt comment to 
refer to _M_attach.
             (_Safe_iterator_base::_M_detach): Fix comment typo.
             (_Safe_iterator_base::_M_detach_single): Adapt comment to 
refer to _M_detach.
             (_Safe_sequence_base::_M_attach_single): Adapt comment to 
refer to _M_attach.
             (_Safe_sequence_base::_M_detach_single): Adapt comment to 
refer to _M_detach.

Tested under Linux x86_64 _GLIBCXX_DEBUG mode just to check that comment 
is still consider as such.
