Hi,

This patch adds support to the AArch64 back-end for the Cortex-A35
processor, as recently announced by ARM. The ARM Cortex-A35 provides
full support for the ARMv8-A architecture, including the CRC extension,
with optional Advanced-SIMD and Floating-Point support. We therefore set
feature flags for this CPU to AARCH64_FL_FOR_ARCH8 and AARCH64_FL_CRC, in
the same fashion as Cortex-A53 and Cortex-A57. While the Cortex-A35
supports dual-issue, we model it as single issue with the expectation that
this will give better schedules when sharing the Cortex-A53 pipeline model.

Bootstrapped with --with-cpu=cortex-a35 with no issues.

I'm sorry to have got this upstream a little late for the end of Stage 1,
but if it is OK with the AArch64 maintainers I'd like to get it in for
GCC 6.

OK?

Thanks,
James
