This http://src.chromium.org/viewvc/chrome?revision=276388&view=revision, to
turn on building of browser_tests.exe for Official Windows builds was
rolled-back, because there was a warning related to unreachable code in
pref_hash_browsertest.cc. 

See log file here:
http://build.chromium.org/p/chromium.chrome/builders/Google%20Chrome%20Win/bu...

This CL attempts to fix that warning so that we may then re-enable
browser_tests.exe for official Windows builds.

Thanks.
