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! Differential Revision: http://llvm-reviews.chandlerc.com/D2187 llvm-svn: 195382
