    expr: Use constant_lower_bound classifying constructor els [PR116595].

    In categorize_ctor_elements_1 we do
      VECTOR_CST_NELTS (value).to_constant ()
    but VALUE's type can be a VLA vector (since r15-5780-g17b520a10cdaab).

    This patch uses constant_lower_bound instead.

            PR middle-end/116595

    gcc/ChangeLog:

            * expr.cc (categorize_ctor_elements_1): Use
            constant_lower_bound.

    gcc/testsuite/ChangeLog:

            * g++.target/riscv/rvv/autovec/pr116595.C: New test.
