commit 004c5f4fec78414943d788c2a8b42a4500272949

    Tweak perf-numbers for T1969 and T4801
    
    Right now, Phab's buildbot complains about
    
      Unexpected failures:
        perf/compiler T1969 [stat too good] (normal)
        perf/compiler T4801 [stat not good enough] (normal)
    
    However, on my workstation, those tests don't fail (c.f. P14).
    So this commit tries to blindly tweak those numbers and see if
    if Phabricator succeeds to build this code-revision...
    
    Test Plan: Let Harbormaster build it
