> This was added to ADT in https://reviews.llvm.org/D148367 then reverted in https://reviews.llvm.org/D148547 because it was a layering violation pointed out in https://reviews.llvm.org/D148384#4270356.

This description requires readers to read the links. How about make the description self-contained with a brief message?

Add C++ 20 style starts_with to be used in LLVMDemangle. Due to library layering (LLVMSupport depends on LLVMDemangle), we add the utility header under llvm/Demangle, instead of llvm/ADT or llvm/Support.
