[RS6000] Hookize GO_IF_MODE_DEPENDENT_ADDRESS

[Anatoly Sokolov]

  Hi.

  This patch removes obsolete GO_IF_MODE_DEPENDENT_ADDRESS macro from the
RS6000 back end in the GCC and introduces equivalent
TARGET_MODE_DEPENDENT_ADDRESS_P target hook.

  Regression tested on powerpc64-unknown-linux-gnu.    OK to install?

        * config/rs6000/rs6000.c (rs6000_mode_dependent_address_p): New.
        (TARGET_MODE_DEPENDENT_ADDRESS_P): Define.
        (rs6000_mode_dependent_address_ptr): Make static.
        * config/rs6000/rs6000.h (GO_IF_MODE_DEPENDENT_ADDRESS): Remove.
        * config/rs6000/rs6000-protos.h (rs6000_mode_dependent_address_ptr):
        Remove.
