Original change's description:
> [BrowserSwitcher] Build BHO for both bitnesses
> To do so, this CL also adds support for the x86 toolchain in an x64
> build.
> Instead of generating one DLL, we now generate 2 DLLs in the root
> out-dir:
> - browser_switcher_bho.dll (x86)
> - browser_switcher_bho_64.dll (x64)
> The one that is cross-built (i.e. bitness doesn't match the host) is
> built in a sub-directory, and then copied to the root out-dir.
