For the SSL cert status, convert anonymous enum that gives bit values into a typedefed uint32. This allows code all over Chromium to use an explicit type instead of "int". This also means the individual named bit constants themselves have the same explicit type. I find the resulting code to be noticeably clearer. This also exposed a bug in SSLErrorInfo::GetErrorsForCertStatus() where not having an explicit type allowed a function argument ordering bug to creep in, so I claim this is safer too. 

Normally this makes things like DCHECK_EQ() unhappy, but when I'd originally tested this I didn't seem to need to make any changes due to that. Will be watching the trybots... 

The original motiviation for this change was to find a way to eliminate some cases of passing anonymous-typed values as template arguments (which happens when you use a value from the enum in e.g. EXPECT_EQ()), which is technically illegal in C++03, though we don't warn about it. Simply naming the enum would have done this, but this would have encouraged readers to actually use the enum name as a type, which for a bitfield is inappropriate for the reason given in the first paragraph.
