Yes, I've applied a patch and looks like it helped:
---
Overhead       Samples    Symbol
trunk@252796 + patch
  31.57%        412037    mgau_eval
  30.54%    --> 397608    vector_gautbl_eval_logs3
   9.78%        127468    subvq_mgau_shortlist

And I see in perf that actual execution goes exactly the same way as it goes
for r250415 (corresponding parts of function bodies are actually being
executed).
