When build LLDB on LoongArch used with the following commands:

git clone https://github.com/llvm/llvm-project.git
mkdir -p llvm-project/llvm/build
cd llvm-project/llvm/build
cmake .. -G "Ninja" -DLLVM_TARGETS_TO_BUILD="BPF" \

  -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="LoongArch" \
  -DLLVM_ENABLE_PROJECTS="clang;lldb" \
  -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_BUILD_RUNTIME=OFF

ninja

there exist some build errors:

undefined reference to `lldb_private::process_linux::NativeRegisterContextLinux::DetermineArchitecture(unsigned long)'
undefined reference to `lldb_private::process_linux::NativeRegisterContextLinux::CreateHostNativeRegisterContextLinux(...)'

Add the minimal changes as simple as possible for LoongArch
to fix the above issues, even there are some empty functions,
then the built binary lldb can be found in the build/bin/
directory.

This is the first step, we will submit other more patches
step by step in the future, these small patches make an
easily understood change that can be verified by reviewers.
