vect: Fix regression for PR104116

Browse Source 
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.
