Just call go list twice to get all the dependencies. This immediately

The test was looking for strings found in specific Go versions
without checking for the actual Go version running the test.
Used ReleaseTags to check whether the current go version should
execute a test or not.
P.S. The version info is inferred from the binary running the test.
But the test builds godoc using the "go" binary in $PATH. In case
one is testing different go versions, please ensure to run tests
by changing the $PATH variable to point to different go versions,
rather than using a custom go binary in a different path.

If go list fails because it doesn't support the new flags added
for Go 1.11 (which will be also released in Go 1.10.4) try again
using the Loader to approximate the packages requested.
This implementation is incomplete. It will never support test packages
because of the two phase test loading process of the Loader. It
also doesn't reliably have access to export data so it will
always do an upgraded whole-program query. But we'll try to get
the best level of support we can for the go/packages interface
given the limitations of the loader.
Once Go 1.12 is released, we'll delete this support. By then, most
Go users should have at least switched to Go 1.10.4.

This change reads $GOROOT/api/go1.*.txt when godoc starts and caches
information about which versions of Go introduce functions, types, and
methods. This information is displayed currently only in HTML output.
Functions, types, and methods introduced as part of Go 1 are not
annotated, as their presence at that version is implied.
This change does not address constants or variables, and completely
ignores the syscall package. The former are future work, the latter is
likely an exercise in futility. In all cases, this is because the story
around displaying the version information is not well developed.

yet supports a range of build systems including 'go build', vgo,
Bazel, and Blaze.
This CL contains the API, the "go list"-based implementation, and some
basic tests. More tests, more features as described in doc.go, and
implementations for bazel and blaze will follow.
