Enable SIL parsing and SIL serialization of semantics.
We add one more field to SILFunctionLayout for semantics. We should refactor
handling of attributes at SIL level, right now they are in SILFunction as bool
or std::string and in SIL serializer as a 1-bit field or an ID field.

These types are needed by enough of the stack now that it makes sense to centralize their lookup and caching onto the AST context like other core types.

Mandatory-inlined (aka transparent functions) are still treated as if they
had the location and scope of the call site. <rdar://problem/14845844>
Support inline scopes once we have an optimizing SIL-based inliner

If a source file contains the main class for its module, then implicitly emit a top_level_code that invokes UIApplicationMain with the name of the marked class.

This fixes a case where the Swift-variadic and C-varargs versions of
various initializers were superseding each other
<rdar://problem/16801456>.
It also uncovered some more cases where we weren't getting quite the
right semantics for factory-methods-as-initializers, which are also
fixed here.

Generalize the bridging of AnyObject[] to NSArray into bridging T[] to
NSArray, following what we already have for dictionaries. Use some new
Foundation-level entry points for the bridging, which could use an
audit from someone who understands Array better than I do.
Part of <rdar://problem/16535097>.
Swift SVN r17869
This should be used sparingly , for cases where forming the parameter/result types is tricky due to generics. If we could form those types without too much pain, it'd be better to remove this hack. However, it enables bridging in cases where we need generic bridging.

This was an artifact of their long-dead C++-based implementations that was way past due to clean up. It's also a convenient workaround for <rdar://problem/16835447>, since we no longer have to look up constructor members for String at SILGen time and potentially lazily instantiate Clang-imported types during SILGen. This totally isn't a real solution to that problem, but it puts out the fire for now.

This is part of our poor-man's internal compiler SPI hiding
in the standard library. We don't want these functions showing
up in code completion, etc.
Swift SVN r16916
The implied semantics are:
- side-effects can occur any time before the first invocation.
- all calls to the same global_init function have the same side-effects.
- any operation that may observe the initializer's side-effects must be
preceded by a call to the initializer.
This is currently true if the function is an addressor that was lazily
generated from a global variable access. Note that the initialization
function itself does not need this attribute. It is private and only
called within the addressor.
Swift SVN r16683
Before we create a new initializer, check whether it would collide
with existing initializers. If it's better than the existing
initializer, mark the existing one as unavailable; if it's not better,
don't build it.
In support of this, we tweak a few things w.r.t. unavailble
declarations:
- An unavailable declaration is shadowed by an available one,
- Don't emit SIL unavailable, imported initializers
This fixes the last problem with <rdar://problem/16509024>.

These bits are orthogonal to each other, so combine them into one, and diagnose attempts to produce a type that's both. Spot-fix a bunch of places this revealed by inspection that we would have crashed in SILGen or IRGen if blocks were be handled.

Allows AnyObject[] to occur in @objc methods/properties/etc., then
bridges between the two in SILGen based on the new array
implementation. <rdar://problem/16535097>.
Note that this commit does not change the Clang module importer to
import NSArray* as AnyObject[] (yet).

Make ObjCMutablePointer @objc-able for (potentially optional) class types, and bridge it down to UnsafePointer when calling @objc entry points.
Swift SVN r15838
When we see CConstPointer or CMutablePointer in a foreign function signature, transparently bridge it to UnsafePointer at the foreign entry point, lifetime-extending the C*Pointer value during foreign calls so that its owner reference is held for the duration of the call.
Swift SVN r15602
Add __FUNCTION__ to the repertoire of magic source-location-identifying tokens. Inside a function, it gives the function name; inside a property accessor, it gives the property name; inside special members like 'init', 'subscript', and 'deinit', it gives the keyword name, and at top level, it gives the module name. As a bit of future-proofing, stringify the full DeclName, even though we only ever give declarations simple names currently.
Swift SVN r14710
Inherited initializers are now functional: one can use an inherited
initializer to construct an object of a subclass type, and we properly
handle delegation to overridden complete object or subobject
initializers as appropriate. See the executable test.
This commit also contains various fixes for the IRGen side of vtable
emission and use. Proper IRGen tests still to come.
For now, we're still performing peer delegation from a subobject
initializer to another subobject initializer, hence the SILGen hack
for identifying when we're in a complete object vs. a subobject
initializer. We'll be banning delegation from subobject initializers,
so this hack---along with the peer_method instruction---will be going
away in the near future.

Emit witnesses for initializer requirements. Allow the use of
initializer requirements on archetypes; existentials don't work due to

We should also remove it from IRGen's Explosion API; IRGen
should always use maximal explosion, and SILGen will tell us
whether or not we need to put that in memory somewhere.
But that can be a later commit.

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.

- Add a "isDirectPropertyAccess" bit to DeclRefExpr, serving the
same purpose as MemberRefExprs for non-member properties.
- Teach sema to synthesize correct non-member get/set implementations
for observing properties.
- Teach silgen to handle the isDirectPropertyAccess bit.

Edge SILFunction one step closer to independence from SILFunctionType context by taking the generic param list as a separate constructor parameter, and serializing those params alongside the function record. For now we still pass in the context params from the SILFunctionType in most cases, because the logic for finding the generic params tends to be entangled in type lowering, but this pushes the problem up a step.
Thanks Jordan for helping work out the serialization changes needed.
Compared to r13036, this version of the patch includes the decls_block RecordKind enumerators for the GENERIC_PARAM_LIST layouts in the sil_block RecordKind enumerator, as Jordan had suggested before. r13036 caused buildbot failures when building for iOS, but I am unable to reproduce those failures locally now.
Swift SVN r13485
Importing a transparent definition pulls in references to its local functions and types, so they can't be module-private. Arguably, they should be recursively transparent too, but this is the minimal fix to clear up those annoying 'isExternallyAvailable()' crashes.

with FuncDecls. This allows us to eliminate special case code for handling
self in various parts of the compiler.
This also improves loc info (debug info and AST info) because 'self' now
has a location instead of being invalid.
I also took the opportunity to factor a bunch of places creating self decls
to use similar patterns and less copy and paste code.

This patch:
- Changes sema to set the "IsDirectPropertyAccess" on MemberRefExprs
in inits/destructors that should be done directly because they are
on the local object.
- Removes the "SGF.AlwaysDirectStoredPropertyAccess" bool in SILGen,
which was the source of the problem above and was otherwise problematic.
This will get a bit simpler when -enable-new-objc-properties rolls out.
