Clang doesn't know what to do with the "armv7-none-eabi" triple that you have
specified.  It's warning about that:

clang: warning: unknown platform, assuming -mfloat-abi=soft

The "soft" ABI means that hardware floating-point instructions cannot be used. 
Apparently no one has implemented that for vector operations.  If you specify
-mfloat-abi=softfp, you'll get what you want.

If you want that triple to be recognized, you'll need to update the
Clang::AddARMTargetArgs() function in lib/Driver/Tools.cpp.  I'm going to close
this again, since I don't think we need to keep a bug report open to track
that.
