Jungho Ahn 4d48e5fa3d x/crypto/poly1305: add ARM assembly 
This change adds ARMv6 assembly implementation. The referenced assembly code was
  the public domain source by Andrew Moon in https://github.com/floodyberry/poly1305-opt/blob/master/app/extensions/poly1305/poly1305_armv6-32.inc.
  The author has confirmed that it's ok to put it under the Go license.

  Benchmark results on Raspberry Pi (ARMv6-compatible processor rev 7),
   o Without ARMv6 assembly

     Benchmark64     50000       38880 ns/op     1.65 MB/s

   o With ARMv6 assembly

Adam Langley 9c0a3ae199 go.crypto/poly1305: enable AMD64 assembly 
This change alters the assembly to use FSUBD instructions such that
6l will actually emit the correct FSUBRD instructions and enables
the assembly code.
