The headers provided with recent GNU toolchains for PPC have code that includes typedefs such as:
`typedef _Complex float __cfloat128 __attribute__ ((__mode__ (__KC__)))`

Also, when I added `__float128`, I neglected to add support for `_Complex __float128` altogether. This patch fixes those oversights and allows clang to compile something like:

  #include <math.h>
  _Complex __float128 testkf(_Complex __float128 a, _Complex __float128 b) {
    return a + b;
  }

with `-mfloat128` which it currently fails to compile due to the two reasons listed above.
