[lldb] Move redundant persistent variable counter to ClangPersistentVariables
Currently Target::m_next_persistent_variable_index is counting up for our persistent variables ($0, $1, ...) but we also have a unused counter that is supposed to do this in ClangPersistentVariables but that stays always at 0 (because we currently increase the target counter when we should increase that unused counter). This patch removes the counter in Target and lets the documented counter in ClangPersistentVariables do the variable counting. Patch *should* be NFC, but it might unexpectedly bring LLDB to new code paths that could contain exciting new bugs to fix. llvm-svn: 367842
