Implement P0035R4, C++17 new of over-aligned types.
gcc/cp/
* cp-tree.h (enum cp_tree_index): Add CPTI_ALIGN_TYPE.
(align_type_node): New macro.
* call.c (build_operator_new_call): Handle C++17 aligned new.
(second_parm_is_size_t, build_op_delete_call): Likewise.
(non_placement_deallocation_fn_p): Likewise. Rename to
usual_deallocation_fn_p.
(aligned_allocation_fn_p, aligned_deallocation_fn_p): New.
* decl.c (cxx_init_decl_processing): Add aligned new support.

* c-cppbuiltin.c (c_cpp_builtins): Handle aligned new.
libstdc++-v3/
* libsupc++/new: Declare aligned new/delete operators.
* config/abi/pre/gnu.ver: Export them.
* configure.ac: Check for aligned_alloc, posix_memalign, memalign,
_aligned_malloc.
