Functions
lldb::ValueObjectSP	LookupIdentifier (llvm::StringRef name_ref, std::shared_ptr< StackFrame > frame_sp, lldb::DynamicValueType use_dynamic)
	Given the name of an identifier (variable name, member name, type name, etc.), find the ValueObject for that name (if it exists), excluding global variables, and create and return an IdentifierInfo object containing all the relevant information about that object (for DIL parsing and evaluating).
lldb::ValueObjectSP	LookupGlobalIdentifier (llvm::StringRef name_ref, std::shared_ptr< StackFrame > frame_sp, lldb::TargetSP target_sp, lldb::DynamicValueType use_dynamic)
	Given the name of an identifier, check to see if it matches the name of a global variable.
