  Bump sanitizer macOS deployment target to 10.10

Bump default value for `SANITIZER_MIN_OSX_VERSION` to 10.10 (from 10.9).
TSan does not work on macOS 10.9 and a nice error message is preferable
to an "unreferenced symbol" error when loading the TSan runtime.

We could try to only bump the deployment target for TSan, but we would
have to invest into adding support for this to our CMake build and it
does not seem worth it.  macOS 10.10 was released in 2014.

  Bump sanitizer iOS deployment target to 9.0

Bump default value for `-miphoneos-version-min=x` to 9.0 (from 8.0).
TSan tests that use thread local storage `__thread` (e.g., tls_race.cpp)
are failing to link for the iOS simulator (arch=x86_64 and
-miphoneos-version-min=8.0) on internal/master (will be submitted to
Glacier train):
```
ld: targeted OS version does not support use of thread local variables in _main for architecture x86_64
```

iOS 9.0 was released 2015.
