- deleted IsType
- inlined + deleted: ValueOf, TypeCaseVar, ImportSpecPkg
- on failure, TypeOf accessor now returns nil (was: panic)
go/ssa: avoid extra map lookups by using Uses or Defs directly when safe to do so,
and keeping the TypeAndValue around in expr0().

which do not appear in the function's instruction lists, and fixes two

We introduce a method (*Interface).Complete(), which is intended
to be called from clients after all embedded interfaces have been
fully defined. For importers, this will definitely be the case
after the import has finished, so each importer have been updated
to do so, with the exception of the gcimporter, which does not use
embedded interfaces, therefore Complete() can be called immediately
after construction.
Building the method set separately from the constructor type caused
some problems with go/importer, which copies the types.Interface
object, leading to there existing two almost-identical interface
types referenced from interface method receivers, only one of which
has been completed. To avoid this situation, the importer has been
modified to construct the interface object only once.
Fixesgolang/go#8177.

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"
}

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.

to correctly link against imported packages.
This also adds support for the condensed import data format

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.
