The `ap` suffix is a remnant of lldb's former use of auto pointers, before they got deprecated. Although all their uses were replaced by unique pointers, some variables still carried the suffix. In r353795 I removed another auto_ptr remnant, namely redundant calls to ::get for unique_pointers. Jim justly noted that this is a good opportunity to clean up the variable names as well. I went over all the changes to ensure my find-and-replace didn't have any undesired side-effects. I hope I didn't miss any, but if you end up at this commit doing a git blame on a weirdly named variable, please know that the change was unintentional. llvm-svn: 353912
