Problem / Steps to reproduce

Profile-guided optimization (PGO), also known as feedback-directed optimization (FDO), is a compiler optimization technique that feeds information (a profile) from representative runs of the application back into to the compiler for the next build of the application, which uses that information to make more informed optimization decisions. For example, the compiler may decide to more aggressively inline functions which the profile indicates are called frequently.

Enabling PGO usually result in somewhere between 2-14% better performance, I think it would be interesting to enable this for fzf.
