Makes it possible for client code to maintain its own profiles,
and also reduces the API surface by giving us a type that
models built-in profiles.

Using reg as the flag word was unfortunate, since the
default value is not 0 but NREG (==16), which happens
to be the bit NOPTR now.  Clear it.

Not a Go 1 issue, but appeared to be fairly easy to fix.

- Note that a few existing test cases look slightly worse but
  those cases were not representative for real code. All real
  code looks better now.

- Manual move of the comment in go/scanner/example_test.go
  before applying gofmt.

- gofmt -w $GOROOT/src $GOROOT/misc
