Increase MSVC warning level to 4.
There are some exceptions, a subset of the exceptions used by Chromium. They didn't seem to be useful warnings.
In code which we don't change much, like the preprocessor, I just suppressed the warnings in the specific files rather than changing the code.
There should be no functional changes in this patch.
