[PATCH] D53857: [cfi] Support sanstats if binary is not available in the original location

[Vitaly Buka via Phabricator via llvm-commits]

By default sanstats search binaries at the same location where the were when
stats was collected. Sometime you can print report immediately or need to move
post-processing to another workstation. To support this use-case if original binary is missing sanstats will fall-back to directory with sanstats file.
