Re: [abc] PLDI paper

Here are the intraprocedural numbers.

noopt means no intraproc optimizations
sharing means sharing only
shar+cnt means sharing and using counters
all3 means sharing, using counters, and -cflow-share-thread-locals

"new" (not threadlocal)
            noopt sharing shar+cnt all3
figure 1219.82 285.22 139.29 24.56
quicksort 122.02 75.58 28.39 27.51
sablecc 30.52 30.11 23.83 22.72
ants 21.25 21.31 21.21 18.73
lod-sim 1741.00 50.35 34.75 26.58
lod-weka 1495.65 155.02 102.33 74.65
conastack 689.40 91.99 52.60 29.07
conasim 76.11 75.56 73.49 72.11

"threadlocal"
            noopt sharing shar+cnt all3
figure 1074.36 238.68 90.26 20.35
quicksort 122.06 75.08 27.86 27.41
sablecc 29.65 29.75 23.31 23.05
ants 19.03 19.27 18.96 17.95
lod-sim 1723.44 46.47 32.92 25.99
lod-weka 1351.21 143.32 92.20 74.84
conastack 594.46 80.00 41.13 27.24
conasim 75.54 75.34 73.54 71.95

The times are just from one run each, for now, not average-of-5.
