Operands returns the SSA values used by an instruction.
Referrers returns the SSA instructions that use a value, for
some values.  These will be used for SSA renaming, to follow.

Previously merely printing an error would cause the golden
file comparison (in 'bash run') to fail, but that is no longer
the case with the new run.go driver.

The lowering of ast.RangeStmt now has three distinct cases:

1) rangeIter for maps and strings; approximately:
    it = range x
    for {
      k, v, ok = next it
      if !ok { break }
      ...
    }
   The Range instruction and the interpreter's "iter"
   datatype are now restricted to these types.

2) rangeChan for channels; approximately:
    for {
      k, ok = <-x
      if !ok { break }
      ...
    }

3) rangeIndexed for slices, arrays, and *array; approximately:
    for k, l = 0, len(x); k < l; k++ {
      v = x[k]
      ...
    }

In all cases we now evaluate the side effects of the range expression
exactly once, per comments on http://code.google.com/p/go/issues/detail?id=4644.

However the exact spec wording is still being discussed in
https://golang.org/cl/7307083/.  Further (small)
changes may be required once the dust settles.

Details:
- reorder.go: delete p8.
  (Once expectation is changed per b/4627 it is identical to p1.)
- switch.go: added some more (degenerate) switches.
- range.go: improved error messages in a few cases.
- method.go: added tests of calls to promoted methods.

Simplify the internal logic for flags controlling what to vet,
by introducing a map of flags that gathers them all together.
This change should simplify the process of adding further flags.

Add a test for untagged struct literals.
Delete a redundant test that was also in the wrong file.
Clean up some ERROR patterns that weren't working.

"make test" passes again.

This CL provides the rest of the SetCookies code as well as
some test infrastructure which will be used to test also
the Cookies method. This test infrastructure is optimized
for readability and tries to make it easy to review table
driven test cases.

Tests for all the different corner cases of SetCookies
will be provided in a separate CL.

By default, crypto/x509 assumes that users wish to validate
certificates for ServerAuth. However, due to historical reasons,
COMODO's intermediates don't specify ServerAuth as an allowed key
usage.

Rather NSS and CryptoAPI both allow these SGC OIDs to be equivalent to
ServerAuth.
