    c++: Use fold_non_dependent_expr rather than maybe_constant_value in
__builtin_shufflevector handling [PR106001]

    In this case the STATIC_CAST_EXPR expressions in the call aren't
    type nor value dependent, but maybe_constant_value still ICEs on those
    when processing_template_decl.  Calling fold_non_dependent_expr on it
    instead fixes the ICE and folds them to INTEGER_CSTs.
