Sjoerd Meijer 342bbb7832 [FuncSpec] Don't specialise functions with NoDuplicate instructions. 
getSpecializationCost was returning INT_MAX for a case when specialisation
shouldn't happen, but this wasn't properly checked if specialisation was
forced.

Chuanqi Xu 86906304d8 [FuncSpec] Use std::pow instead of operator^ 
The original implementation calculating UserBonus uses operator ^, which means XOR in C++
language.
At the first glance of reviewing, I thought it should be power, my bad.
It doesn't make sense to use XOR here. So I believe it should be a
carelessness as I made.

Test Plan: check-all

Sjoerd Meijer 9907746f5d Move Function Specialization to its correct location. NFC. 
As a follow up of rGc4a0969b9c14, and as part of D104102, move it to
the IPO transformations directory.
