Possible UB in reading coverage mapping with compressed function names
...reading coverage
mapping serialized in v2 format (with compressed function names).
I committed my patch, r266436, using the current format for .covmapping
file, and then buildbots complained about it:

Hi Dennis!
clang-x64-ninja-win7 fails for some time on
1. UNRESOLVED: UBSan-Standalone-x86_64::log-path_test.cc
<http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/4522/steps/ninja%20check%201/logs/UNRESOLVED%3A%20UBSan-Standalone-x86_64%3A%3Alog-path_test.cc>
this masks other new test failuers (clang modules related). Could you have
a look?

Also see http://llvm.org/bugs/show_bug.cgi?id=20815.
The error reports look vaild: in general it's incorrect to load uint64_t,
or even structures like "RawHeader" or "CoverageMappingTURecord" from a
random address. Also, if you parse files stored on disk, it woul...
