Buggy optimizers are part of my problem set, too.

You're probably right in this case, but surely in *some* cases, it is
appropriate to let the programmer give the compiler hints about how to
optimize.  The compiler is still doing the error-prone part (deciding
whether the optimization is correct, and actually performing the
transformation).  The programmer is merely suggesting that the
optimization is worthwhile.
