now that they are implicitly updated. This exposes two things:
1) we're unncessarily serializing selfdecls in ctors and dtors.
2) The index pattern of a SubscriptDecl has no sensible DeclContext that
owns variables in it.
I'll deal with the first tomorrow, I'm not sure what to do with
the second one.

all of their generic parameters. This simplifies logic creating them,
allowing us to eliminate all setDeclContext() calls from the parser.
While we're at it, change Parser::addVarsToScope to be a static
function in ParseStmt.cpp and dramatically cut it down since none of
its remaining clients are using most of its capabilities. It needs
to be simplified even further.

for loop that walks the pattern variables and sets them up.
Move addVarsToScope to ParseStmt.cpp which is what is left
using it.
Add a new "addAccessorsInOrder" helper to add the get/set
accessors to the Decls tree in the right order.

Allow IfStmts and WhileStmts to have as their condition either an expression, as usual, or a pattern binding introduced by 'var' or 'let', which will conditionally bind to the value inside an optional. Unlike normal pattern bindings, these bindings require an in-line initializer, which will be required to be Optional type. Parse variable bindings in this position, and type-check them by requiring an Optional on the right-hand side and unwrapping it to form the pattern type. Extend SILGen's lowering of if and while statements to handle conditionally binding variables.

Switch some diagnostic text from 'static' over to 'type' to make
things easier, and fix up some parsing issues with selector-style
declarations found by doing this. NFC

arguments. Until we have @inout methods on structs, we can't mark anything
that can be address-exposed. This temporarily regresses a few testcases,
but they will come back later.

var decls. I was originally intending to use this for argument lists, but I
don't think that's a great direction to go anymore.
In any case, it seems uncontroversial to enforce immutability on foreach
enumation patterns, so I did that (see testcase)

The contexts for which we set the DisallowStoredVar bit, currently enums and extensions, can both (theoretically) support static variables, so change PD_DisallowStoredVar to PD_DisallowStoredInstanceVar, and allow static vars to be declared in these contexts.

Previously, the Parser and BranchStmt typedef-ed ExprStmtOrDecl as a pointer union. Using typedef made the objects compatible, but did not allow us to extend the type with helper methods, such as getSourceRange(), which is something you can get on all of the AST objects. This patch introduces ASTNode that subclasses from PointerUnion and is used by both parser and BranchStmt.

I tried hard find all references to 'func' in documentation, comments and
diagnostics, but I am sure that I missed a few. If you find something, please
let me know.

This ensures that the brace range will include all contained items.
The previous scheme of choosing the end location of the last item was not accurate because for pattern bindings decls
we also push the var decls as items, but they don't have the full source range of the pattern binding decl.
