This patch set includes the following updates from v2 [1]:
. addr_mode_costs table moved into struct tune_params from
  struct cpu_cost_table (avoids overlap with AArch64 port)
. CPU data bus width now comes from a table entry in struct tune_params.
  (Not intended to be 100% accurate, but sufficient for this
  patch series)
. test cases for {pre,post}-indexed addressing

    https://gcc.gnu.org/ml/gcc-patches/2017-08/msg01519.html

Charles Baylis (3):
  [ARM] Add bus_width_bits to tune_params
  [ARM] Refactor costs calculation for MEM.
  [ARM] Add table of costs for AAarch32 addressing modes.
