<pre>If the optimizer decides to remove a loop that's tagged with "#pragma clang
loop vectorize(enable)", then some kind of diagnostic should be issued, instead
of silence as the case currently.
If/since the pragma is explicitly there, the programmer is obviously
expecting/requiring vectorization, so if that's not performed, she should be
warned.
This is related to PR28374.</pre>
