Include LLD project to build and run the tests together with LLVM expensive checks on all appropriate builders:
- llvm-clang-x86_64-expensive-checks-ubuntu
- llvm-clang-x86_64-expensive-checks-win
- llvm-clang-x86_64-expensive-checks-debian
- llvm-clang-x86_64-expensive-checks-ubuntu-release
- llvm-clang-x86_64-expensive-checks-win-release
- llvm-clang-x86_64-expensive-checks-debian-release
The LLD test use the expensive check data structures and it would be good to detect the failures when they configured with -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON (ref: D105071)
