    Fix PR 10153: tail recusion for vector types.

    The problem here is we try to an initialized value
    from a scalar constant. For vectors we need to do
    a vect_dup instead.  This fixes that issue by using
    build_{one,zero}_cst instead of integer_{one,zero}_node
    when calling create_tailcall_accumulator.

    Changes from v1:
    * v2: Use build_{one,zero}_cst and get the correct type before.

    OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.

    gcc/ChangeLog:

            PR tree-optimization/10153
            * tree-tailcall.c (create_tailcall_accumulator):
            Don't call fold_convert as the type should be correct already.
            (tree_optimize_tail_calls_1): Use build_{one,zero}_cst instead
            of integer_{one,zero}_node for the call of
create_tailcall_accumulator.
