Merged from revision b638b63b99d66786cb37336292604a2ae3490cfd. The patch successfully bootstraps on x86_64-linux-gnu and ppc64le-linux-gnu. I also tested ppc64-linux-gnu that exposed: https://reviews.llvm.org/D80864 (which is fixed on master). Abidiff looks happy and I made UBSAN and ASAN bootstrap on x86_64-linux-gnu. I'm planning to do merge from master twice a year, once now and next time short before stage1 closes. I am going to install the patches as merge from master is obvious and I haven't made anything special. libsanitizer/ChangeLog: * MERGE: Merge from master.
