Hongtao Yu 34e131b0f2 [llvm-profgen] On-demand track optimized-away inlinees for preinliner. 
Tracking optimized-away inlinees based on all probes in a binary is expansive in terms of memory usage I'm making the tracking on-demand based on profiled functions only. This saves about 10%  memory overall for a medium-sized benchmark.

This should be a no-diff change in terms of profile quality.
