For now, only do this in SourceKit (printQuickHelpDeclaration), but
there are probably other printing modes that should do this.

Move the type callbacks into the respective type/typerepr printers so
taht we get these callbacks even when we print the type directly, or in
a nested fashion. Also make the returntype more explicit than just
"inside a function type", since visiting the function type currently
visits the input argument tuple (which is different than e.g. the
function *decl* printing, which walks the parameter list explicitly).

As a first foray into annotating attribute, add tags around attribute
names. For now, treat any decl-modifiers as keywords. We will also want
to wrap the whole attribute (including any parameters) into tags as
well, but that will require more work in the callback hanlding.
Also factor the attribute printing to handle any special cases early,
which will simplify wrapping attributes in tags, since we can then just
put the whole switch intside the pre/post callbacks.

Try to match the original spelling of static/class in diagnostics and
when printing the AST. Also fixes cases with
PrintOptions.PrintImplicitAttrs = false, where we would just print
'class', which was not valid code.
When the LHS is an lvalue/assignable tuple and there is no leading
sequence of binary expressions.
It's a bit hacky right now since we don't have a good way to
differentiate general pattern completions from builtin operators.

In the experimental operator completion, we were mysteriously missing
some operators like ||. It turns out it was all operators
alphabetically after '.', because the filtering code was very broken.

Also expose the printing function as a SwiftLangSupport static method.
Ideally we could move this into libIDE, but it currently depends on the
UIdent visitor to get decl-specific tag names and it's not obvious how
we should hoist/abstract that out in a nice way.

The problem was that shouldPrint returned true, but shouldPrintInContext
returned false, so we called printDeclPost without ever printing
anything and therefore never calling the pending printDeclPre. Also
remove the avoidPrintDeclPost in the annotation printer, since it was
incorrectly assuming that avoidPrintDeclPost was paired with
printDeclPre (it's not clear to me that it isn't sometimes paired
though...).
Future work: remove or properly document the difference between the two
shouldPrint* variants; and ensure that callbacks will always be paired
even if we don't end up printing anything. Also verify that
avoidPrintDeclPost behaves correctly with respect to printDeclPre being
called (or not).
