Comment (by carter):

 Ok, I'll amend the patch so that the XMM and YMM stanzas are the same for
 32bit and 64bit x86.

 Current 32bit x86 GHC's will still work correctly because they spill all
 the floating point values to the stack, and I guess we'll figure out
 manpower wise doing the work to synch up the native code gen to support
 floating point args too.
