* Added build flags for compiling DPDK on ARM * Added sse2neon as a submodule for translating Intel SSE intrinsics to Arm/Aarch64 NEON implementation: https://github.com/DLTcollab/sse2neon * Implemented SSE4.2 _mm_cmpstri as not supported by sse2neon. Adapted from: https://github.com/apache/impala/blob/master/be/src/util/sse-util.h * Added equivalent arm64 asm for x86_64 asm.

Arm/Aarch64 NEON implementation.

All tests passed except
TscToUs.Frequencyas on ARM reported tsc_hz is 50MHz (cross checked withmrs x0, cntfrq_el0instruction which returns Timer Counter Frequency register). This is failing as the test requires frequency >= 500MHz.Closes #1028
