libstdc++: Implement ranges [specialized.algorithms]
This implements all the ranges members defined in [specialized.algorithms]:
ranges::uninitialized_default_construct
ranges::uninitialized_value_construct
ranges::uninitialized_copy
ranges::uninitialized_copy_n
ranges::uninitialized_move
ranges::uninitialized_move_n
ranges::uninitialized_fill
ranges::uninitialized_fill_n
ranges::construct_at
ranges::destroy_at
ranges::destroy
It also implements (hopefully correctly) the "obvious" optimizations for these
algos, namely that if the output range has a trivial value type and if the
appropriate operation won't throw then we can dispatch to the standard ranges
version of the algorithm which will then potentially enable further
optimizations.
libstdc++-v3/ChangeLog:
* include/Makefile.am: Add <bits/ranges_uninitialized.h>.
* include/Makefile.in: Regenerate.
* include/bits/ranges_uninitialized.h: New header.
* include/std/memory: Include it.
* testsuite/20_util/specialized_algorithms/destroy/constrained.cc: New
test.
* .../uninitialized_copy/constrained.cc: New test.
* .../uninitialized_default_construct/constrained.cc: New test.
* .../uninitialized_fill/constrained.cc: New test.
* .../uninitialized_move/constrained.cc: New test.
* .../uninitialized_value_construct/constrained.cc: New test.
