Revert "Fix lldb option handling since e953ae5bbc313fd0cc980ce021d487e5b5199ea4 (part 2)" Revert "Fix lldb option handling since e953ae5bbc313fd0cc980ce021d487e5b5199ea4" GCC build hangs on this bot https://lab.llvm.org/buildbot/#/builders/37/builds/19104 compiling CMakeFiles/obj.clangBasic.dir/Targets/AArch64.cpp.d The bot uses GNU 11.3.0, but I can reproduce locally with gcc (Debian 12.2.0-3) 12.2.0. This reverts commit caa713559bd38f337d7d35de35686775e8fb5175. This reverts commit 06b90e2e9c991e211fecc97948e533320a825470. This reverts commit e953ae5bbc313fd0cc980ce021d487e5b5199ea4.
