cmd/stringer: use strconv instead of fmt

In the generated code, we want to pull in as few dependencies as
possible. fmt is heavier than strconv, and the latter can be used with a
bit of extra code for the same results.

More importantly, this will allow stringer to be used in some std
packages that cannot import fmt, such as regexp/syntax. While strconv
lies in L2 in deps_test.go, fmt lies in L4.

This means that many other packages will also be able to use stringer
where it could be useful, such as path/filepath, os/exec, or io/ioutil.

Since some of these types may be 64-bit integers, use FormatInt instead
of Itoa to avoid overflows with int on 32-bit.

Also double-checked that the generated code is still formatted properly.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
