All DImode constant on hammer are 32bit sign extended except for the move.
We play similar games with constant in SImode, whose may or may not be 8bit.
I really want to make mode represent real size computation is done in,
since then it is usable for other purposes, such as detecting need for 16/32
32/64 prefixes and partial register stalls.

I will install rest of the patch minus those hunks.
Thanks!
