[Bug c/30475] assert(int+100 > int) optimized away

Oh, so C++ code using vector gets faster, you say?  Let's see...

This is vector.C from http://ptrace.fefe.de/vector.C

It does some assignments to a vector.  It runs the loop 10 times and takes the
minimum cycle counter.

  $ g++ -O2 -o vector vector.C
  $ ./vector
  20724 cycles
  $ g++ -O2 -o vector vector.C -fwrapv
  $ ./vector
  20724 cycles
  $

And AGAIN you are proven wrong by the facts.  Do you have some more "proof"
where this came from?

Man, this is ridiculous.  Just back out that optimization and I'll shut up.
