[PATCH]middle-end: correct loop bounds for early breaks and peeled vector loops

Hi All, While waiting for reviews I've continued to run more test. In this case this was one found running 32-bit systems. While we calculate the right latch count for the epilog, the vectorizer overrides SCEV and so unrolling goes wrong. This updates the bounds for the case where we've peeled a
