[PATCH 3/4][AArch64] Add scheduling model for Exynos M1

[Evandro Menezes]

    2015-11-05  Evandro Menezes <e.menezes@samsung.com>

    gcc/
         * config/aarch64/aarch64-cores.def: Use the Exynos M1 sched model.
         * config/aarch64/aarch64.md: Include "exynos-m1.md".
         * config/arm/arm-cores.def: Use the Exynos M1 sched model.
         * config/arm/arm.md: Include "exynos-m1.md".
         * config/arm/arm-tune.md: Regenerated.
         * config/arm/exynos-m1.md: New file.

This patch adds the scheduling model for Exynos M1.  I split the DFA 
into ones for GP, LS and FP, resulting in many fewer states and arcs 
than before.

Please, commit if it's alright.

Thank you,
