This patch synthesizes haddps/haddpd/hsubps/hsubpd instructions from floating point additions and subtractions of appropriate vector shuffles. To do this I introduced new x86 FHADD and FHSUB opcodes. These need to be wired up somehow in the .td file to the appropriate instructions. Since I have no idea how tablegen works I just hacked it in horribly. It works, but breaks support for the hadd

...bably there is a way to compress this using tablegen magic, but I don't know how. OK to apply?
