Add optimized implementation of mersenne twister for aarch64
2017-07-23 Michael Collison <michael.collison@arm.com>
Add optimized implementation of mersenne twister for aarch64
* config/cpu/aarch64/opt/ext/opt_random.h: New file.
(__arch64_recursion): New function.
(__aarch64_lsr_128): New function.
(__aarch64_lsl_128): New function.
(operator==): New function.
(simd_fast_mersenne_twister_engine): Implement
method _M_gen_rand.
* config/cpu/aarch64/opt/bits/opt_random.h: New file.
* include/ext/random: (simd_fast_mersenne_twister_engine):
add _M_state private array.
