Add support for 64-bit Windows build: base and chrome/app
This is required to support Native Client on 64-bit Windows. Native Client will use a small 64-bit executable to load NaCl modules on 64-bit Windows. This 64-bit executable will use Chrome code, but some functionality has to be removed to minimize dependencies. This functionality may be enabled later if we decide that it is necessary. TEST=None BUG=28176 Review URL: http://codereview.chromium.org/371073 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@33823 0039d316-1c4b-4281-b951-d872f2087c98
