Elliott Hughes 784609317d Mandate optimized __memset_chk for arm and arm64. 
This involves actually implementing assembler __memset_chk for arm64,
but that's easily done.

Obviously I'd like this for all architectures (and all the string functions),
but this is low-hanging fruit...

Bernhard Rosenkraenzer 7e4fa56099 Add ARMv8 optimized string handling functions based on cortex-strings 
This adds ARMv8 optimized string handling functions to Bionic.
The implementations live in a generic/ directory because there will
likely be more CPU specific versions (e.g. Cortex-A53 vs. Cortex-A57)
later.

These implementations are 50%+ faster on current v8 models.
