Remove N3639 "array of runtime length" from -std=c++14.
gcc/cp/
* decl.c (compute_array_index_type): VLAs are not part of C++14.
(create_array_type_for_decl, grokdeclarator): Likewise.
* lambda.c (add_capture): Likewise.
* pt.c (tsubst): Likewise.
* rtti.c (get_tinfo_decl): Likewise.
* semantics.c (finish_decltype_type): Likewise.
* typeck.c (cxx_sizeof_or_alignof_type): Likewise.
(cp_build_addr_expr_1): Likewise.
* init.c (build_vec_init): Don't throw bad_array_length.
gcc/c-family/
* c-cppbuiltin.c (c_cpp_builtins): Define __cpp_runtime_arrays if
we aren't complaining about VLAs.
libstdc++-v3/
* libsupc++/new (bad_array_length): Move...
* bad_array_length.cc: ...here.
* cxxabi.h, eh_aux_runtime.cc (__cxa_throw_bad_array_new_length): Also
move to bad_array_length.cc.
* c-cppbuiltin.c (c_cpp_builtins): Define __cpp_runtime_arrays if
we aren't complaining about VLAs.
