If a word is once deleted, the word never gets into the
personalized dictionaries due to this bug.

5c4bec31d1 Enable Address Sanitizer for native host test 2nd try 
This CL enables Address Sanitizer for native host test. Note that
production build is not affected with this change.  ASan is enabled
only in static lib for test executables.

Yohei Yukawa
ba35bb83a8 Stop building host native test in unbundled build 
It turned out that building native code for host environment
is not supported in NDK build.  Hence this CL makes the host
native test available only as a part of platform build to
avoid accidental build breakage in unbundled build.
