ad7a884efe R600/SI: Add kill flag when copying scratch offset to a register 
This allows us to re-use the same register for the scratch offset
when accessing large private arrays.

a978a481bb R600/SI: Don't store scratch buffer frame index in MUBUF offset field 
We don't have a good way of legalizing this if the frame index offset
is more than the 12-bits, which is size of MUBUF's offset field, so
now we store the frame index in the vaddr field.
