[PATCH] middle-end: Drop __builtin_pretech calls in autovectorization [PR114061]'

At present the autovectorizer fails to vectorize simple loops involving calls to `__builtin_prefetch'. A simple example of such loop is given below: void foo(double * restrict a, double * restrict b, int n){ int i; for(i=0; i *references) clobbers_memory = true;
