Enable support for CSPGO for lld MachO targets. Since lld MachO does not support `-plugin-opt=`, we need to create the `--cs-profile-generate` and `--cs-profile-path=` options and propagate them in `Darwin.cpp`. These flags are not supported by ld64. Also outline code into `getLastCSProfileGenerateArg()` to share between `CommonArgs.cpp` and `Darwin.cpp`. CSPGO is already implemented for ELF (https://reviews.llvm.org/D56675) and COFF (https://reviews.llvm.org/D98763). Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D151589
LLVM Linker (lld)
This directory and its subdirectories contain source code for the LLVM Linker, a modular cross platform linker which is built as part of the LLVM compiler infrastructure project.

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
