I found this PR to be the offending one after using git bisect with the cmake invocation:

```cmake -G Ninja ../llvm -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXPORT_COMPILE_COMMANDS=ON '-DLLVM_TARGETS_TO_BUILD=X86;ARM;AArch64' -DLLVM_ENABLE_ASSERTIONS:BOOL=TRUE -DLLVM_ENABLE_MODULES=On -DLLVM_ENABLE_PROJECTS='clang;lld;lldb;cross-project-tests' -DLLVM_VERSION_PATCH=99 '-DLLVM_ENABLE_RUNTIMES=libcxx;libcxxabi;compiler-rt'```

and running `ninja lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/CodeGenPassBuilder.cpp.o `

I am reverting this change for now
