e0d167f1dd libSyntax: create syntax nodes for variable declarations. 
Variable declarations are declarations led by either 'var' or 'let'. It
can contain multiple pattern bindings as children.

For patterns, this patch only creates syntax nodes for simple identifier
patterns, e.g. 'a = 3'. The rest of the pattern kinds are still left
unknown (UnknownPattern).

9ddd60d4ef libSyntax: create syntax nodes for closure signature. (#13415) 
This patch also refactors the structure of function signature node so
that closure signature can re-use parts of function signature. For
instance, we group arrow and return type to be "ReturnClause". And we
group parenthesized parameter list to be "ParamClause".

This structure of closure signature also calls for a good way to
represent either-or node in libSyntax APIs, since we've two ways to
specify parameters in closure: one is as regular function parameter and
the other is dot-separated simple names.

dc5888d887 [parse] Recover better from malformed subscript decls for code-completion 
Code-completion of generic types expects to get a DeclContext for the
subscript, so make sure we recover well enough to produce a
SubscriptDecl.

229f98462e [Parse] Slightly refactor TupleTypeRepr element parsing. 
* Instead of consuming 'inout' unconditionally, use backtracking to
  determine it's obsolete usage of 'inout' position.
* parse '...' before '= <initializer>' because '(Int... = [1])' is more
  likely than '(Int = 1 ...)'. This improves diagnostics.

c4604d700e libSyntax: specialize struct declaration syntax node. (#13307) 
To construct struct syntax, this patch first specialized type
inheritance clause. For protocol's class requirement, we currently
treat it as an unknown type.

This patch also teaches SyntaxParsingContext to collect syntax nodes
from back in place. This is useful to squash multiple decl modifiers
for declarations like function. This is not used for struct declaration
because only accessibility modifier is allowed.

fec040d95e libSyntax: support generic parameter clause. (#13286) 
This patch also performs minor refactoring to align syntax parsing
context with the right scope. We start to support the generic clauses
because they are necessary pieces to construct struct or
function syntax node.
