[GCC-XML] mmx, sse, sse2, sse3, etc...

[Cyrus Harmon]

Thanks for the tip. BTW, my initial attempt at this gives me the  
following in the XML file:

...
   <Unimplemented id="_35793" tree_code="9"  
tree_code_name="vector_type" node="0x7cba80"/>
...

for the following:

  typedef float __m128 __attribute__ ((__vector_size__ (16)));

So it seems that GCC-XML at least recognizes that it can't deal with  
these. I really don't anticipate needing these types anytime soon,  
but rather I'm just trying to get the QuickTime headers to get  
gccxml'ed appropriately on x86/macos. I can probably keep commenting  
out buts until it works, but I thought I would pass this along.
