We improve the efficiency through two ways: 1. read the protocol keywords, such as
http, radar, or im, to select the right regex pattern to search for instead of
trying every known patterns; and 2. reduce the regex search space by truncating
text before protocol keywords. rdar://21009781

Doc comments assume a prefix of /** and a suffix of */
but if a user accidentally types /**/, SourceKit can crash and
bring down Xcode with certain timings. Check both ends of doc
comments before dropping characters.

- Start highlighting doc comments as Xcode "Documentation Comments".
- Start highlighting custom top-level fields as Xcode "Documentation
Comment Keywords".
This requires SourceKit r28827 to build and Xcode
rdar://problem/21034381 for proper highlighting.

instead of being an expression.
To the user, this has a couple of behavior changes, stemming from its non-expression-likeness.
- #available cannot be parenthesized anymore
- #available is in its own clause, not used in a 'where' clause of if/let.
Also, the implementation in the compiler is simpler and fits the model better. This
fixes:
<rdar://problem/20904820> Following a "let" condition with #available is incorrectly rejected

Now that we don't have generic parameter lists at arbitrary positions
within the extended type of an extension declaration, simplify the
representation of the extended type down to a TypeLoc along with a
(compiler-synthesized) generic parameter list.
On the parsing side, just parse a type for the extended type, rather
than having a special grammar. We still reject anything that is not a
nominal type (of course), but it's simpler just to call it a type.
As a drive-by, fix the crasher when extending a type with module
qualification, rdar://problem/20900870.

Change all uses of "do { ... } while <cond>" to use "repeat" instead.
Rename DoWhileStmt to RepeatWhileStmt. Add diagnostic suggesting change
of 'do' to 'repeat' if a condition is found afterwards.

The API review list found it confusing that if #os() and #if os() looked so similar, so
change the availability checking query to be spelled #available:
if #available(iOS >= 9.0, *) {
...
}

Previously, a multi-pattern var/let decl like:
var x = 4, y = 17
would produce two pattern binding decls (one for x=4 one for y=17). This is convenient
in some ways, but is bad for source reproducibility from the ASTs (see, e.g. the improvements
in test/IDE/structure.swift and test/decl/inherit/initializer.swift).
The hardest part of this change was to get parseDeclVar to set up the AST in a way
compatible with our existing assumptions. I ended up with an approach that forms PBDs in
more erroneous cases than before. One downside of this is that we now produce a spurious
"type annotation missing in pattern"
diagnostic in some cases. I'll take care of that in a follow-on patch.

- Rename getParentPattern() -> getParentPatternBinding(), since
it returns the pattern binding, not the pattern.
- Introduce new getParentPattern()/getParentInitializer() methods,
covering the most common uses of getParentPatternBinding().

The eventual goal for extensions of generic types is to require them
to specify their generic parameters, e.g.,
extension Array<T> { ... }
rather than today's
extension Array { ... }
Start parsing (optional) generic parameters here, and update the
representation of ExtensionDecl to accomodate this new grammar
production. Aside from the parser changes, there's no intended
functionality change here.
