    Fix handling of VEC_COND_EXPR trap tests [PR100284]

    Now that VEC_COND_EXPR has normal unnested operands,
    operation_could_trap_p can treat it like any other expression.

    This fixes many testsuite ICEs for SVE, but it turns out that none
    of the tests in gcc.target/aarch64/sve were affected.  Anyone testing
    on non-SVE aarch64 therefore wouldn't have seen it.

            * tree-eh.c (operation_could_trap_p): Handle VEC_COND_EXPR rather
            than asserting on it.
