R600 Patches: .td file cleanups and compute fixes for Cayman

[Vincent Lejeune]

The serie is reviewed-by:Vincent Lejeune<vljn at ovi.com>

I think that we can drop the "useCustomInserter" modifier though,
we always set the eop bit in the last NOP instruction in R600ControlFlowFinalizer Pass ;
we could modify R600CFF later to allow it to mark the last export/memwrite as eop.

In my opinion the eop should be set as late as possible : although the order of the
export/rat_cacheless_write instruction is not modified until R600CFF pass at the moment, 
some future optimizations (like a pass that will merge export instructions using burst count)
may be easier to write if it does not have to deal with non default eop bit.
