Summary: This patch adds initial code completion support for the `expr` command. We now have a completion handler in the expression CommandObject that essentially just attempts to parse the given user expression with Clang with an attached code completion consumer. We filter and prepare the code completions provided by Clang and send them back to the completion API. The current completion is limited to variables that are in the current scope. This includes local variables and all types used by local variables. We however don't do any completion of symbols that are not used in the local scope (or in some other way already in the ASTContext). This is partly because there is not yet any code that manually searches for additiona information in the debug information. Another cause is that for some reason the existing code for loading these additional symbols when requested by Clang doesn't seem to work. This will be fixed in a future patch.
