File containing the reproduceable case
When building the attached file with clang-cl using the flags "/Od /Zi" and
running the output with the Visual Studio 15 2017 debugger, evaluating `this`
at line 8 (before initialization) gives the result "Variable is optimized away
and not available.". This behaviour is different to both clang+lldb and pure
MSVC, both of which give `this` the address of the uninitialized object. This
occurs whether the MSVC linker or lld is used.
clang version 10.0.0
Target: x86_64-pc-windows-msvc
Thread model: posix</pre>
