    vect: Initialize new_temp to avoid false positive warning [PR110652]

    As PR110652 and its duplicate PRs show, there could be one
    build error

      error: 'new_temp' may be used uninitialized

    for some build configurations.  It's a false positive warning
    (or error at -Werror), but in order to make the build succeed,
    this patch is to initialize the reported variable 'new_temp'
    as NULL_TREE.

            PR tree-optimization/110652

    gcc/ChangeLog:

            * tree-vect-stmts.cc (vectorizable_load): Initialize new_temp as
            NULL_TREE.
