Poly1305 ARM32 NEON: add implementation

Browse Source 
Add assembly for Poly1305 using ARM32 NEON instruction set.

For Poly1305 ARM32 Base:
  Change name from poly1305_blocks_arm32_16 to poly1305_arm32_blocks_16

poly1305.c:
  ARM32 NEON - buffer up to 4 blocks
  x86_64 - only calculate powers of r once after key is set.
test.c: poly1305 testing with multiple updates.
benchmark: chacha20-poly1305 now uses AAD
