Revert of clang/win: Fix a few warnings in targets not in chromium_builder_tests. (patchset #3 id:40001 of https://codereview.chromium.org/526513002/)

Reason for revert:
Speculative, might have broken InstallerStateTest.InitializeTwice on XP: http://build.chromium.org/p/chromium.win/builders/XP%20Tests%20%281%29/builds/32481

InstallerStateTest.InitializeTwice (run #1):
[ RUN      ] InstallerStateTest.InitializeTwice
c:\b\build\slave\win_builder\build\src\chrome\installer\util\installer_state_unittest.cc(639): error: Value of: wcsstr(installer_state.target_path().value().c_str(), BrowserDistribution::GetSpecificDistribution( BrowserDistribution::CHROME_BINARIES)-> GetInstallSubDir().c_str())
  Actual: false
Expected: true
[  FAILED  ] InstallerStateTest.InitializeTwice (219 ms)

InstallerStateTest.InitializeTwice (run #2):
[ RUN      ] InstallerStateTest.InitializeTwice
c:\b\build\slave\win_builder\build\src\chrome\installer\util\installer_state_unittest.cc(639): error: Value of: wcsstr(installer_state.target_path().value().c_str(), BrowserDistribution::GetSpecificDistribution( BrowserDistribution::CHROME_BINARIES)-> GetInstallSubDir().c_str())
  Actual: false
Expected: true
[  FAILED  ] InstallerStateTest.InitializeTwice (109 ms)
