<pre>Summary: Building LLVM for 32-bit Win32, using MSVC 2019, on recent trunk
builds, crashes the compiler.
This is using the most recent MSVC 2019 Community Edition on a Win10 x86-64
box:
```
$ vcvarsall.bat x64_x86
$ cmake -G Ninja C:/path/to/llvm-project/llvm -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX=C:/path/to/llvm-install -DLLVM_BUILD_32_BITS=ON
-DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_LIBXML2=OFF
-DLLVM_ENABLE_PROJECTS=clang;lld -DLLVM_ENABLE_RTTI=ON
-DLLVM_ENABLE_TERMINFO=OFF
-DLLVM_TARGETS_TO_BUILD=X86;ARM;NVPTX;AArch64;Mips;Hexagon;PowerPC;WebAssembly
$ ninja -C C:/path/to/llvm-build -j 18 install
```
this chugs away for quite some time, but eventually fails building
clang-tblgen, with:
```

I don't (yet) have an injection point for when the failure started occurring,
but it was sometime within the past week. I'll update this bug if/when I find
one.</pre>
