  Revert "Recommit "[Clang] Pragma vectorize_width() implies vectorize(enable)""

This reverts commit 80371c74ae63d2f260bcc75408be9c6f81e38465.

Given the following source:
```
void a() {
  for (;;)
    ;
}
```

It incorrectly enables vectorization (with vector width 1), as well as generating a warning that vectorization could not be performed.
