This page seems to document them:

http://gcc.gnu.org/onlinedocs/gccint/Machine-Modes.html

Quote:
QCmode, HCmode, SCmode, DCmode, XCmode, TCmode
These modes stand for a complex number represented as a pair of floating point values. The floating point values are in QFmode, HFmode, SFmode, DFmode, XFmode, and TFmode, respectively.

I'll take care of this.

Fixed in r65935.
