[PATCH] D22261: [InlineCost] Set minsize inline threshold to 0

Hi,

I re-ran testing, again using test-suite -Oz, but this time targetting T32 (thumb mode 32-bit). This time I do get differences:

  Trunk -Oz: find . -name '*.o' | xargs size | awk '{sum+=$1} END {print sum}'
  10080358
  
  Trunk -Oz -mllvm -inline-threshold=0:  find . -name '*.o' | xargs size | awk '{sum+=$1} END {print sum}'
  7722119

For completeness, I also tried this with Clang-3.7:

  3.7 -Oz: 6919363
  3.7 -Oz -mllvm inline-threshold=0: 7820357

So 3.7 -Oz was a lot better than trunk -Oz and there were indeed regressions when setting the threshold to 0. But now we've bloated a lot and we get improvements.
