<pre>When running a two-stage ThinLTO build on Windows, where the second stage uses
these commands:
> set OPT_SKYLAKE=/GS- /D_ITERATOR_DEBUG_LEVEL=0 -Xclang -O3 -Xclang
-fwhole-program-vtables -fstrict-aliasing -march=skylake-avx512
> cmake "-DLLVM_LIT_ARGS=-sv -j 36" -G"Ninja" %ROOT%/llvm
-DCMAKE_BUILD_TYPE=Release -DLLVM_OPTIMIZED_TABLEGEN=true
-DLLVM_ENABLE_LIBXML2=OFF -DLLVM_USE_CRT_RELEASE=MT
-DCMAKE_C_COMPILER="%STAGE1%/bin/clang-cl.exe"
-DCMAKE_CXX_COMPILER="%STAGE1%/bin/clang-cl.exe"
-DCMAKE_LINKER="%STAGE1%/bin/lld-link.exe" -DLLVM_ENABLE_LLD=ON

-DLLVM_ENABLE_LTO=THIN -DCLANG_TABLEGEN="%STAGE1%/bin/clang-tblgen.exe"

> ninja check-all
The test `hurd.c` fails. I will post a fix shortly.
Occurs in release/10.x.</pre>
