Yi Kong 2f5f16d574 Tweak ThinLTO inling heuristics in absense of PGO profile 
We previously disabled inlining and unrolling completely during ThinLTO
in absense of PGO profile. For global ThinLTO, we want to better balance
binary size and performance.

We evaluated a number of combination of heuristics with global ThinLTO
configuration:
                                binary size change
  no LTO                          baseline
  no inline, no unroll            -0.54%
  no inline, unroll               -0.50%
  import-instr-limit=5, unroll    +0.02%
  import-instr-limit=10, unroll   +0.13%

Loop unrolling does not contribute much to the binary size, therefore
it is re-enabled.

import-instr-limit=5 balances the binary size savings from ThinLTO and
size incrase due to additional optimisation.
