New make target "testshort" runs "gotest -test.short" and is invoked by run.bash, which is invoked by all.bash. Use -test.short to make one package (crypto ecdsa) run much faster. More changes to come. Once this is in, I will update the long-running tests to use the new flag. R=rsc CC=golang-dev https://golang.org/cl/4317043
