This logs all successful handshakes and all requests to run code snippets;
it is not immediately obvious how to limit this to non-localhost hosts, or
to instances where publicly available playgrounds are allowed without resorting
to addition of a new global. The level of noise on the log should not be too
great.

This CL introduces two vet checks. Statistics and code below are from a recent 50mb corpus of public code.
1. Check for redundant conjunctions and disjunctions. This check caught 26 instances, of which 20 were clearly copy/paste bugs and 6 appeared to be mere duplication. A typical example:
if xResolution < 0 || xResolution < 0 {
panic("SetSize(): width < 0 || height < 0")
}
2. Check for expressions of the form 'x != c1 || x != c2' or 'x == c1 && x == c2', with c1 and c2 constant expressions. This check caught 16 instances, of which all were bugs. A typical example:
if rf.uri.Scheme != "http" || rf.uri.Scheme != "ftp" {
rf.uri.Scheme = "file"
}
Fixesgolang/go#7622.

This builtin is a little weird in this form as it is (to my knowledge)
the only function that takes a variadic argument of non-slice
type. The language provides no syntax to express this, so we pick
a stringification for such arguments that does not appear in the
language. Specifically, use T... instead of ...T to distinguish it
from the normal case where the type is a slice.
This change lets the go/ssa package produce more efficient IR by
avoiding an extra conversion of the second argument.

This also adds support for the condensed import data format
where the priority information is stored as a suffix of the

Bare init functions omit calls to dependent init functions and the
use of an init guard. They are useful in cases where the client uses
a different calling convention for init functions, or cases where
it is easier for a client to analyze bare init functions.

Previously, statements such as:
type T struct { a, b int }
[...]
x = T{}
x = T{b: 1}
would only affect the aggregate members mentioned in the composite
literal and leave the other members unchanged. This change causes us
to write a zero value to the target in cases where the target is not
already known to hold a zero value and the number of initializers in
the composite literal differs from the number of elements in its type.

Before, Load() would just fail. Now, it gathers all frontend
errors (not just the first go/types error) in PackageInfo.Errors.
There are still cases where Load() can fail hard, e.g. errors in x_test.go
files. That case is trickier to fix and remains a TODO item.
Also, make godoc display all scanner/parser/type errors in the source view.

In command godoc, set IndexEnabled when the -write_index flag is set.
Previously you would need to (unintuitively) set the -http flag to
achieve this.
In package godoc, set up the FS tree before loading the index, and
then return before starting the index refresh loop. Previously the
index would be loaded and then immediately refreshed, negating the
benefits of the on-disk index.

This removes much of the AST logic out of main.go,
and makes it easier to build custom vet binaries
The trade-off in this change is for flexibility.
There's very little change in the per-check files,
a lot less code in main.go (specifically the AST walking
logic has shrunk), and it makes it much easier to build
custom vet binaries simply by dropping new source files
in the directory.
