Summary: To get the target order correct, the benchmarks directory has been moved one level higher. Previously, it was living in the utils directory. The utils directory is a collection of utils which are to be used by the tests and implementations. However, benchmarks *use* the implementations. So, moving it out of utils helps us setup proper target level dependencies. Reviewers: gchatelet Differential Revision: https://reviews.llvm.org/D81910
