Language features like erasing concrete metatype
values are also left for the future. Still, baby steps.
The singleton ordinary metatype for existential types
is still potentially useful; we allow it to be written
as P.Protocol.
I've been somewhat cavalier in making code accept
AnyMetatypeType instead of a more specific type, and
it's likely that a number of these places can and
should be more restrictive.
When T is an existential type, parse T.Type as an
ExistentialMetatypeType instead of a MetatypeType.
An existential metatype is the formal type
\exists t:P . (t.Type)
whereas the ordinary metatype is the formal type
(\exists t:P . t).Type
which is singleton. Our inability to express that
difference was leading to an ever-increasing cascade
of hacks where information is shadily passed behind
the scenes in order to make various operations with
static members of protocols work correctly.
This patch takes the first step towards fixing that
by splitting out existential metatypes and giving
them a pointer representation. Eventually, we will
need them to be able to carry protocol witness tables

recursive positions.
Also change the representation of certain <global>s in the
demangling tree by sinking <directness> down as a child of
the affected node.

A short-term fix to <rdar://problem/16079822> that keeps generic overloads from creating symbol collisions without requiring a larger migration of the debugger or other tools.
Swift SVN r14353
This is more in line with all other modules currently on our system.
If/when we get our final name for the language, we're at least now set
up to rename the library without /too/ much trouble. (This is mostly just
a lot of searching for "import swift", "swift.", "'swift'", and '"swift"'.
The compiler itself is pretty much just using STDLIB_NAME consistently now,
per r13758.)
<rdar://problem/15972383>
Swift SVN r14001
We allow overloads on foo(() -> T) and foo(@auto_closure () -> T) in Sema, so they need distinct manglings. Fixes <rdar://problem/16045566>.
Swift SVN r13856
Implement the demangling for generic signatures and their requirements, dependent parameters, and member types, now that we actually use these manglings when naming reabstraction thunks.
Swift SVN r13764
This is mostly useful for the standard library, whose name is going to
change to "Swift" soon. (See <rdar://problem/15972383>.) But it's good DRY.
Swift SVN r13758
This time, be sure to reset the demangler state after demangling the
specialization header, because it is a prefix of the demangled symbol
name.
Swift SVN r13378
- Int and UInt are now struct types backed by Builtin.Word. Previously they
were typealiases for Int64; Int and Int64 are now distinct types.
- Mangled names 'i' and 'u' are now Int and UInt. Int64 is mangled longhand.
- Word is a typealias for Int. It is expected to go away in the future.
- Builtin.Word is unchanged.
- CLong and CUnsignedLong are typealiases for Int and UInt.
- FixedPoint.swift is now FixedPoint32.swift and FixedPoint64.swift.
Reunifying these requires better builtins, especially for checked
conversions (rdar://15472770).
- Updated many tests, mostly because Int is no longer spelled Int64 in sil.
- One check was removed from test decl/operator/operators.swift
because it changed behavior when Int became a non-typealias
type (rdar://15934688).
Swift SVN r13109
type, so we emit them. Add mangler (and demangler) support for these.
Enhance our testcase to check to make sure that stores within these
specifiers are direct, they don't cause recursive infinite loops.
John, I picked w/W for the mangling letters, let me know if this is ok.

When we're using Objective-C's memory allocation, emit .cxx_construct
methods whenever we have instance variables with in-class
initializers. Presently, these methods are just empty stubs.
Swift SVN r12211
The Objective-C runtime executes the .cxx_destruct method after the
last -dealloc has executed when destroying an object, allowing the
instance variables to remain live even after the subclass's
destructor/-dealloc has executed, which is important for memory
safety. This fixes the majority of <rdar://problem/15136592>.
Note that IRGenModule::getAddrOfIVarDestroyer() contains an egregious
hack to find the ivar destructor SIL function via a linear
search. We need a better way to find SIL functions that we know exist,
because LinkEntity does not suffice.
Swift SVN r12206
Revert "add a hackaround for rdar://15753317. I don't unerstand the code enough to tell if this is the right fix."
This reverts commit 416983b0734dde6979c98971948068c7a157e336.

Not NFC: changes some of the demangling tree schemata (in
interest of regularity and expressivity) and, incidentally,
improves support for initializer manglings.
The main schema change is that Path is now gone, and instead
the first child of an entity is its context. All contexts
are now labelled with their kind (variable/function/etc.)
rather than that being much more obscure or missing.
A secondary change is that the top-level node is now a
single node with the <global> and all its attributes as
children, rather than being weirdly sibling-linked.
Also, the representation has changed so that nodes link
only to their children, not to siblings or parents, which
means that it is no longer necessary to clone nodes when
replacing substitutions.
Finally, dump/print was brought in from swift-demangler
and made part of the core API for debugging purposes.
Swift SVN r11470
iVars of a given type should be unique by name and so in certain cases, their types will not actually add information to a consumer of the demangled string
This mode is mostly useful for LLDB. When searching for a field offset by name in a generic scenario, the search can succeed or fail depending on whether archetypes are
obtained through the Demangler ("A","B","C") or through the module (which will vend proper archetype names when poked the right way)
This mode removes that ambiguity

decl context of the type alias.
This implements <rdar://problem/15290346> "typealias sugar needs to be
mangled into debug info mangled type names".
