cmd/stringer: accept simple type conversion expressions in constant ValueSpec

This permits constants of the form `const X = T(A)` to add `X` to the
stringer output for type `T`.

While those constants can be rewritten as `const X T = T(A)`, that
becomes tedious and visually noisy when `T` is a long name. It is quite
easy to address this easy and common case, while not attempting to solve
this with full generality.

Fixes #11581.

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.
