Recent changes in the runtime caused the interpreter to call 'getg',
and it should never have gotten that far.
Also, delete bodies of "runtime" functions, since they're too magical.
This makes missing intrinsics cause very obvious failures.

It returns the value formerly returned by Pkg(), i.e. the imported package.
Pkg() now returns the package enclosing the import statement,
which is consistent with all other Objects.

LookupFieldOrMethod now also decides whether a found
method is actually in the method set. Simplifies call
sites. Added corresponding API tests.
TODO (separate CL): Decide what the correct value for
the indirect result should be (as required for code
generation). For now, the result value for indirect
is unchanged from before if a field/method is found.

(1) support Example functions defined in programs that don't
import "testing". We emit code to testmain.main() to call
them directly, since we can't call testing.Main.
(2) expose a FindTests function which reports the set of
Test, Example and Benchmark functions it finds.
Certain clients need this.
Added test for logic in FindTests.

Previously these were recorded in the PackageInfo, but not
reported to the user's error handler (types.Config.Error),
which is typically what prints them.
Minor subtlety: that function must now be able to handle error
values that are not of type types.Error.

Examples:
- "foo$1" becomes "pkg.foo$1"
- "init$1" (meaning the first declared "init" function) becomes "init#1",
to distinguish it from "init$1" (meaning the first anonymous function
within the synthetic "init" function that initializes package-level vars).
It is now an invariant that all source-level (non-synthetic)
functions have distinct names, and that all names include the
enclosing package. Added test for this.

If an expression is addressable, we compute its address then load, rather than
extracting the value of subelements. For aggregates this avoids large copies.
Example:
var x [2]struct{y [3]int}
print(x[1].y[2])
Was:
t0 = local [3]struct{x [5]int} (x) *[3]struct{x [5]int}
t1 = *t0 [3]struct{x [5]int}
t2 = t1[1:int] struct{x [5]int}
t3 = t2.x [#0] [5]int
t4 = t3[2:int] int
Now:
t1 = &t0[1:int] *struct{x [5]int}
t2 = &t1.x [#0] *[5]int
t3 = &t2[2:int] *int
t4 = *t3 int
Also:
- make emitFieldSelections responsible for calling emitDebugRef, as
one of its two calls was forgetting to do it.
- relax the specification of (*Program).VarValue because not all
subexpressions are materalized as values now.
- fix up the objlookup.go test expectations to match.
go/ssa/interp test runs 10% faster.

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.

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.
