Downgrade 'attribute ignored when parsing type' from error to warning, to match

the diagnostic's warn_ name. Switch some places (notably C++11 attributes)
which really wanted an error over to a different diagnostic. Finally, suppress
the diagnostic entirely for __ptr32, __ptr64 and __w64, to avoid producing
diagnostics in important system headers.
