Remove the hack for AARCH64_EXTRA_TUNE_ALL.

2015-08-24  Andrew Pinski  <apinski@cavium.com>

        * config/aarch64/aarch64-tuning-flags.def: Remove all index to
        AARCH64_EXTRA_TUNING_OPTION.
        * config/aarch64/aarch64-protos.h (aarch64_extra_tuning_flags_index): New enum.
        (aarch64_extra_tuning_flags): Base the shifted value on the index instead
        of the argument to AARCH64_EXTRA_TUNING_OPTION.
        * config/aarch64/aarch64.c: Remove the last argument to
        AARCH64_EXTRA_TUNING_OPTION.
