assembler: Replace struct dst_operand by struct brw_reg

Browse Source 
One more step on the road to replacing all register-like structures by
struct brw_reg.

Two things in this commit are worth noting:

* As we are using more and more brw_reg, a lot of the field-by-field
  assignments can be replaced by 1 assignment which results is a
  reduction of code

* As the destination horizontal stride is now stored on 2 bits in
  brw_reg, it's not possible to defer the handling of DEFAULT_DSTREGION
  (aka (int)-1) when setting the destination operand. It has to be done
  when parsing the region and resolve_dst_region() is a helper for that
  task.
