Hi All,

We build LLVM on MSVC to detect compiler regression. On the new repo
https://github.com/llvm/llvm-project/commits/master, we found error C2440 when
building LLVM under /std:c++latest mode, can you help look? Thanks.

build steps:
1. open VS2019 x64 tools command 
2. git clone https://github.com/llvm/llvm-project LLVM
3. cd LLVM
4. mkdir build_x64 && pushd build_x64
5. cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0
-DLLVM_ENABLE_PROJECTS="clang" ..\llvm
6. set _CL_=/std:c++latest
7. msbuild /maxcpucount:4 /p:Platform=x64 /p:Configuration=RelWithDebInfo
/p:PreferredToolArchitecture=x64 ALL_BUILD.vcxproj /t:Rebuild

error info:
GenericTaintChecker.i
F:\gitP\llvm\llvm-project\clang\lib\StaticAnalyzer\Checkers\GenericTaintChecker.cpp(126):
