Clang*: Workaround parsing mingw's <type_traits> with clang 3.9

...for -std=gnu++0x.

Define the unknown identifier/type "__float128" so at least the headers can be
parsed successfully. Of course this does not help for parsing client code
referencing that identifier, but this should be the less common case.
