    vect: Fix regression for PR104116

    The commit gcc-16-4464-g6883d51304f added 30 new tests for testing
    vectorization of {FLOOR,MOD,ROUND}_{DIV,MOD}_EXPR. Few of them failed
    for certain targets due to the vectorization of runtime-check loop which
    was not intended.
    This patch disables optimization for all of the run-time check loops so
    that the count of vectorized loop is always 1.
