[AArch64] Add Saphira pipeline description.

Hi!

Please find attached the patch to add a pipeline description for the
Qualcomm Saphira core.  It is tested with a bootstrap and make check,
with no regressions.

Ok for trunk?

gcc/
Changelog:

2018-10-26 Sameera Deshpande <sameera.deshpande@linaro.org>

* config/aarch64/aarch64-cores.def (saphira): Use saphira pipeline.
* config/aarch64/aarch64.md: Include saphira.md
* config/aarch64/saphira.md: New file for pipeline description.

-- 
- Thanks and regards,
  Sameera D.

I agree that there is a need to have some mechanism to maintain the
architectures which have many commonalities.
However, Saphira and Falkor are very different to have lot of sharing,
and with further performance tuning for Saphira, the differences will
be more prominent.
I will commit this patch as is for saphira, and will look at the
possible factoring for Saphira and Falkor pipelines, with
commonalities and differences when the tuning for Saphira is done.
