[PATCH] Improve std::fill for vector<bool>

[François Dumont]

Hi

I am not clear about current stage so I am proposing this trivial patch 
to find out if we are back in stage 1.

This patch extend the overload so that it is used even when 
_GLIBCXX_DEBUG mode is activated.

             * include/bits/stl_algobase.h (struct _Bit_iterator): New 
declaration.
             (std::__fill_a1(_Bit_iterator, _Bit_iterator, const 
bool&)): Likewise.
             * include/bits/stl_bvector.h (__fill_bvector): Move outside
             _GLIBCXX_STD_C namespace.
             (fill(_Bit_iterator, _Bit_iterator, const bool&)): Likewise 
and rename
             into...
             (__fill_a1): ...this.
             * testsuite/25_algorithms/fill/bvector/1.cc: New.

Tested under Linux x86_64 normal and debug modes.

Ok to commit ?

François
