Roll forward support for ARM intrinsics in crc_memcpy
This CL rolls forward a previous change which we rolled back temporarily due to
compilation errors on x86 when PCLMUL intrinsics were unavailable.
*** Original change description ***
This change replaces inline x86 intrinsics with generic versions that compile
for both x86 and ARM depending on the target arch.
This change does not enable the accelerated crc memcpy engine on ARM. That will
be done in a subsequent change after the optimal number of vector and integer
regions for different CPUs is determined.
