chacha20,poly1305,chacha20poly1305: set consistent build tags
...
appengine was only necessary for the legacy system based on Go 1.9, drop
that. Add purego tags instead. Remove redundant architecture tags.

poly1305: improve performance with asm for ppc64le
...
This adds an asm implementation for poly1305 on ppc64le, based on
the amd64 asm implementation using the mac interface.
The improvements on a power8 based on the poly1305 benchmarks are:

poly1305: implement a subset of the hash.Hash interface
...
This CL adds the poly1305.MAC type which implements a
subset of the hash.Hash interface. With MAC it is possible
to compute an authentication tag of data without copying
it into a single byte slice.
This commit modifies the reference/generic and the
AMD64 assembler but not the ARM/s390x implementation
to support an io.Writer interface.
Updates golang/go#25219
