Paul E. Murphy 6c21748958 internal/poly1305: extend ppc64le support to ppc64 
The cipher needs to load the stream in LE order. Use the byte
reversing loads on BE.

Also, remove the unused variable poly1305Mask in the PPC64
asm file too.

Garrett Bodley bcb0f91bbc internal/poly1305: Port sum_amd64.s to Avo 
This implementation utilizes the same registers found in the reference
implementation, aiming to produce a minimal semantic diff between the
Avo-generated output and the original hand-written assembly.

To verify the Avo implementation, the reference and Avo-generated
assembly files are fed to `go tool asm`, capturing the debug output into
corresponding temp files. The debug output contains supplementary
metadata (line numbers, instruction offsets, and source file references)
that must be removed in order to obtain a semantic diff of the two
files. This is accomplished via a small utility script written in awk.

Commands used to verify Avo output:

GOROOT=$(go env GOROOT)
ASM_PATH="internal/poly1305/sum_amd64.s"
REFERENCE="b2d3a6a4b4d36521cd7f653879cf6981e7c5c340"

go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \
  <(git cat-file -p "$REFERENCE:$ASM_PATH") \
  > /tmp/reference.s

go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \
  "$ASM_PATH" \
  > /tmp/avo.s

normalize(){
  awk '{
    $1=$2=$3="";
    print substr($0,4)
  }'
}

diff <(normalize < /tmp/reference.s) <(normalize < /tmp/avo.s)

Lynn Boger 1a865804d5 x/crypto/internal/poly1305: improve sum_ppc64le.s 
This contains a few minor improvements to sum_ppc64le.s
which result in up to 10% performance improvement for
some of the benchmarks in this directory.

- ADDZE followed by ADD can be combined into ADDE
- PCALIGN added to the loop
- Eliminate a few unnecessary register moves

Sebastiaan van Stijn 08396bb92b internal/poly1305: drop Go 1.12 compatibility 
Other packages already dropped compatibility with go1.12, so it should be safe to remove it for this package as well.

Dmitri Shuralyov 8779cbd1c9 all: update go directive to 1.18 
Done with:

go get go@1.18
go mod tidy
go fix ./...

Using go1.21.3.

Also update avo to v0.5.0 in the curve25519/internal/field/_asm module.
It's newer and produces no diff in the generated code.

For golang/go#60268.
