Second attempt to add iterator_range::empty()

Authored by jordan_rose on Oct 3 2019, 6:35 PM.



Doing this makes MSVC complain that empty(someRange) could refer to either C++17's std::empty or LLVM's llvm::empty, which previously we avoided via SFINAE because std::empty is defined in terms of an empty member rather than begin and end. So, switch callers over to the new method as it is added.

Previously: rL361944

LGTM - this builds on VS now. I think you'll need to rebase against AMDGPURegisterBankInfo.cpp as several additional empty() calls appear to have appeared.
