The primary difference I see between my own build invocation and the buildbot is that it passes `-DLLDB_TEST_USER_ARGS=...`. I'll try mimicking those to see if that works. But, if it's alright, I think I'd like to respond to @jmorse's review comments and commit this patch, and add an lldb regression test in a separate follow-up patch.

For reference, here is what I am using to build locally for testing: 

$ xcrun cmake -G Ninja -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo -DLLVM_ENABLE_ASSERTIONS:BOOL=TRUE -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DLLVM_ENABLE_MODULES=On -DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra;libcxx;libcxxabi;lldb;compiler-rt;lld;debuginfo-tests' ../llvm

maybe that helps!
