[dev.simd] simd/_gen/simdgen: rewrite etetest.sh

Browse source 
Now that simdgen is in the main repo, the end-to-end test script can
be much simpler, more robust, and faster.

# files in this repo and then runs several tests.
This is an end-to-end test of Go SIMD. It checks out a fresh Go XEDDATA="${XEDDATA:-xeddata}"
repository from the go.simd branch, then generates the SIMD input if [[ ! -d "$XEDDATA" ]]; then
files and runs simdgen writing into the fresh repository. echo >&2 "Must either set \$XEDDATA or symlink xeddata/ to the XED obj/dgen directory."
exit 1
fi
After that it generates the modified ssa pattern matching files, then which go >/dev/null || exit 1
builds the compiler. goroot="$(go env GOROOT)"
if [[ ! ../../../.. -ef "$goroot" ]]; then
# We might be able to make this work but it's SO CONFUSING.
echo >&2 "go command in path has GOROOT $goroot"
exit 1
