Reid Kleckner 701593f1db [sancov] Instrument reachable blocks that end in unreachable ...

Summary:
These sorts of blocks often contain calls to noreturn functions, like
longjmp, throw, or trap. If they don't end the program, they are
"interesting" from the perspective of sanitizer coverage, so we should
instrument them. This was discussed in https://reviews.llvm.org/D57982.
