[Intel-gfx] [PATCH 34/90] assembler: Use subreg_nr to store the address register subreg

Another step towards using struct brw_reg for source and destination
operands.
Instead of having a separate field to store the sub register number of
the address register in indirect access mode, we can reuse the subreg_nr
field that was only used for direct access so far.
