IIUC, this patch makes mvectorize-with-neon-quad effectively a no-op 
which is ok with me.

If this is now the default, what is the behaviour of 
-mno-vectorize-with-neon-quad now ? Should that set the value of the 
parameter to 64 or should we be rejecting the negative of that option ?

If not, we should then consider adding a RejectNegative to that option.
