This PR is in reference to porting LLDB on AIX. Link to discussions on llvm discourse and github: 1. https://discourse.llvm.org/t/port-lldb-to-ibm-aix/80640 2. https://github.com/llvm/llvm-project/issues/101657 The complete changes for porting are present in this draft PR: https://github.com/llvm/llvm-project/pull/102601 - Added testcase for `GetProgramFileSpec()` & `FindProcesses()` - Added changes to get the host information for AIX (info like FindProcessesImpl() GetProgramFileSpec()), continue from the PR https://github.com/llvm/llvm-project/pull/134354
