[Bug target/20020] x86_64 - 128 bit structs not targeted to TImode

I think that #19566 is a real bug.  The ABI specifies to pass 16byte 
structs in registers.  Anyway MAX_FIXED_MODE_SIZE doesn't influence 
the calling convention, only how such struct is handled by transforming 
code.  I.e. changing MAX_FIXED_MODE_SIZE shouldn't fix any ABI bug 
(in fact shouldn't change how parameters are passed at all). 
At least from my understanding and if there aren't other bugs making this 
false ;)
