We want authors to be able to publish code that works with both
the current standard go command and the planned new go command
support for modules. If authors have tagged their code v2 or later,
semantic import versioning means the import paths must include a
v2 path element after the path prefix naming the module.
One option for making this convention compatible with original go get
is to move code into a v2 subdirectory of the root.
That makes sense for some authors, but many authors would prefer
not to move all the code into a v2 subdirectory for a transition and
then move it back up once we everyone has a module-aware go command.
Instead, this CL teaches the old (non-module-aware) go command
a tiny amount about modules and their import paths, to expand
the options for authors who want to publish compatible packages.
If an author has a v2 of a package, say my/thing/v2/sub/pkg,
in the my/thing repo's sub/pkg subdirectory (no v2 in the file system path),
then old go get continues to import that package as my/thing/sub/pkg.
But when go get is processing code in any module (code in a tree with
a go.mod file) and encounters a path like my/thing/v2/sub/pkg,
it will check to see if my/thing/go.mod says "module my/thing/v2".
If so, the go command will read the import my/thing/v2/sub/pkg
as if it said my/thing/sub/pkg, which is the correct "old" import path
for the package in question.
This CL will be back-ported to Go 1.10 and Go 1.9 as well.
Once users have updated to the latest Go point releases containing
this new logic, authors will be able to update to using modules
within their own repos, including using semantic import paths
with vN path elements, and old go get will still be able to consume
those repositories.
This CL also makes "go get" ignore meta go-import lines using
the new "mod" VCS type. This allows a package to specify both
a "mod" type and a "git" type, to present more efficient module
access to module-aware go but still present a Git repo to the old
"go get".

On architectures where G is stored in a register, it is
possible for a variable to allocated to it, and subsequently
that variable may be spilled and reloaded, for example
because of an intervening call. If such an allocation
reaches a join point and it is the primary predecessor,
it becomes the target of a reload, which is only usually
right.
Fix: guard all the LoadReg ops, and spill value in the G
register (if any) before merges (in the same way that 387
FP registers are freed between blocks).

In https://go-review.googlesource.com/c/go/+/114317 (fix for #25301)
the constructor types.NewInterface was replaced with NewInterface2.
The new constructor aggressively verified that embedded interfaces
had an underlying type of interface type; the old code didn't do
any verification. During importing, defined types may be not yet
fully set up, and testing their underlying types will fail in those
cases.
This change only verifies embedded types that are not defined types
and thus restores behavior for defined types to how it was before
the fix for #25301.

vet's buildtag check looks for malformed build tag comments. Since these
can appear in Go files as well as non-Go files (such as assembly files),
it must read the file line by line instead of using go/token or go/ast
directly.
However, this method runs into false positives if there are any lines in
the code that look like comments, but are not. For example:
$ cat f.go
package main
const foo = `
//+build ignore
`
$ go vet f.go
./f.go:3: +build comment must appear before package clause and be followed by a blank line
This bug has been popping up more frequently since vet started being run
with go test, so it is important to make the check as precise as
possible.
To avoid the false positive, when checking a Go file, cross-check that a
line that looks like a comment actually corresponds to a comment in the
go/ast syntax tree. Since vet already obtains the syntax trees for all
the Go files, it checks, this change means very little extra work for
the check.
While at it, add a badf helper function to simplify the code that
reports warnings in the buildtag check.
