Alexander Neumann f6a608df62 poly1305/arm: allow building with Go 1.3 
This is the same as https://golang.org/cl/154120043

Since the file textflag.h is not available on Go 1.3, the macros defined
in textflag.h are replaced with their respective value.

Fixes golang/go#11448

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.
