To get this to work, delay some "cleanup" work in the
demangler. For example, we now preserve in the tree
whether something was mangled as an allocating
initializer, and we only special-case the class vs.
non-class cases in the pretty printer.
Also fixes a number of remangling bugs, of course.

Changing the design of this to maintain more local context

Locally scoped type declarations were previously not serialized into the
module, which meant that the debugger couldn't reason about the
structure of instances of those types.
Introduce a new mangling for local types:
[file basename MD5][counter][identifier]
This allows the demangle node's data to be used directly for lookup
without having to backtrack in the debugger.
Local decls are now serialized into a LOCAL_TYPE_DECLS table in the
module, which acts as the backing hash table for looking up
[file basename MD5][counter][identifier] -> DeclID mappings.
New tests:
* swift-ide-test mode for testing the demangle/lookup/mangle lifecycle
of a module that contains local decls
* mangling
* module merging with local decls

a non-native owner. This is required by Slice, which
will use an ObjC immutable array object as the owner
as long as all the elements are contiguous.
As part of this, I decided it was best to encode the
native requirement in the accessor names. This makes
some of these accessors really long; we can revisit this
if we productize this feature.
Note that pinning addressors still require a native
owner, since pinning as a feature is specific to swift
refcounting.
Swift SVN r24420
Change all the existing addressors to the unsafe variant.
Update the addressor mangling to include the variant.
The addressor and mutable-addressor may be any of the
variants, independent of the choice for the other.
SILGen and code synthesis for the new variants is still
untested.

I am starting to reuse manglings for different passes. I want to make sure that
when we reuse functions we actually get a function created by the same pass.

Now all SIL function specialization passes use the new mangling infrastructure.
Lets keep it that way for future passes as well. = ).

This is apart of creating the infrastructure for creating special manglings for
all of the passes that we specialize. The main motiviations for this
infrastructure is:
1. Create an easy method with examples on how to create these manglings.
2. Support multiple specializations. This is important once we allow for partial
specialization and can already occur if we perform function signature
optimizations on specialized functions.
The overall scheme is as follows:
_TTS<MANGLINGINFO>__<FUNCNAME>
Thus if we specialize twice, the first specialization will just be treated as
the function name for the second specialization.
<MANGLINGINFO> is defined as:
_<SPECIALIZATIONKINDID>_<SPECIALIZATIONUNIQUEINFO>
Where specialization kind is an enum that specifies the specific sort of
specialization we are performing and specialization unique info is enough
information to ensure that the identity of the function is appropriately
preserved.
Swift SVN r23801
Note that the demangling for 'a' accessors changes from
'addressor' to 'mutableAddressor'. This is correct for
the existing use-case of global variables, which permit
modification through the result.

They may be backreferenced by contexts nested inside the generic context, namely closures. Fixes the remainder of rdar://problem/18306777.

We currently mangle private declarations exactly like public declarations,
which means that private entities with the same name and same type will
have the same symbol even if defined in separate files.
This commit introduces a new mangling production, private-decl-name, which
includes a discriminator string to identify the file a decl came from.
Actually producing a unique string has not yet been implemented, nor
serialization, nor lookup using such a discriminator.
Part of rdar://problem/17632175.
Swift SVN r21598
If a method is defined within an extension of a class or struct that is
defined in a different module, we mangle the module where the extension is
defined.
If we define function f in module A, and redefine it again in an extension in
module B, we use different mangling to prevent linking in the wrong
SILFunction.

eliminating the @'s from them when used on func's. This is progress towards
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword
This also consolidates rejection of custom operator definitions into one
place and makes it consistent, and adds postfix "?" to the list of rejected
operators.
This also changes the demangler to demangle weak/inout/postfix and related things
without the @.

- Change the parser to accept "objc" without an @ sign as a contextual
keyword, including the dance to handle the general parenthesized case.
- Update all comments to refer to "objc" instead of "@objc".
- Update all diagnostics accordingly.
- Update all tests that fail due to the diagnostics change.
- Switch the stdlib to use the new syntax.
This does not switch all tests to use the new syntax, nor does it warn about
the old syntax yet. That will be forthcoming. Also, this needs a bit of
refactoring, which will be coming up.

There's a lot more work to do here, but start to categorize tests
along the lines of what a specification might look like, with
directories (chapters) for basic concepts, declarations, expressions,
