Working in project that uses build tags

[dadgar]

Behavior

When working in files that have build tags, not much works. There is the command :GoBuildTags but it isn't pervasive. It would be nice if when you set that completion, go-to's, etc worked. This also applies to test files as well. If I set the build tag and run :GoTestFunc it would be nice for those to be applied rather than having to write :GoTestFunc -tags <tag> every time.

Steps to reproduce:

1. Create two files, one guarded by a build tag foo and a main.go
2. Define a struct in the build tag version
3. Set :GoBuilldTag foo
4. Try using the struct in the main.go, autocomplete, goto, etc won't work.

Configuration

• vimrc: Don't think it will be necessary to repro
• vim version: nvim v0.2.0
• vim-go version: Latest
• go version: 1.9.0

Yeah, :GoBuildTags is somewhat inconsistently applied at the moment.

For the most part adding this should be simple; although some tools may not (fully) support it. For example gocode (which is used for the completion) doesn't seem to: nsf/gocode#390

#1562 added support of g:go_build_tags to the :GoTest family of functions.

@Carpetsmoker do you know of any other tools that vim-go uses that we need to add this support to, or should we close this issue since #1562 took care of the :GoTest family of functions?

If this issue is closed it would be nice to see other followup issues be filed for other features that break. I listed a few (goto, autocomplete, etc).
