Introduce two command-line flags for the instrumentation pass to control whether the labels of pointers should be ignored in load and store instructions The new command line flags are -dfsan-ignore-pointer-label-on-store and -dfsan-ignore-pointer-label-on-load. Their default value matches the current labelling scheme. Additionally, the function __dfsan_union_load is marked as readonly. Patch by Lorenzo Martignoni!

DataFlowSanitizer; LLVM changes. DataFlowSanitizer is a generalised dynamic data flow analysis. Unlike other Sanitizer tools, this tool is not designed to detect a specific class of bugs on its own. Instead, it provides a generic dynamic data flow analysis framework to be used by clients to help detect application-specific issues within their own code.
