Commit Message

TinyLfu should admit only if greater frequency

I had written TinyLfu to admit if the candidate's frequency is greater
or equal to the victim's. It turns out that changing this to be greater
only has a nice impact.

- cs: 15.6% --> 26.6% (LIRS: 30.4%)
- gli: 23.16 --> 30.61% (LIRS: 33.6%)
- loop: 0% --> 43.7% (LIRS: 48.9%)
- multi2: 47.9% --> 48.4% (LIRS: 50.1%)
- wikipedia: 57.7% --> 57.8% (LIRS: 57.1%)

The negative impact is minimal. The following degradations were observed.
- sprite: 76% --> 74.9% (LIRS: 76%)
- ps: 56.1% --> 56.0% (LIRS: 57.4%)
- gcc: 91.6% --> 91.4% (LIRS: 90.1%)
- multi3: 41.7% --> 39.8% (LIRS: 44.5%)
