Revert "afdo: Remove -fprofile-sample-accurate flag" 

This reverts commit febf8b9b.

We are still seeing flaky performance alerts from microbenchmarks even
with this change, and this has caused binary size / memory usage
increase. Let's add this flag back and observe whether performance
regression reports become more frequent.
