This code as written is not sound and should not type check
for non-final classes conforming to SequenceType (eg, NSArray).
Instead, capture the base of the call from the preprocess closure
passed in. The closure is @noescape, so it should be equivalent.

Revert "Fix a swift argument initialization bug - swift argument should be initialized"
This reverts commit 273b149583.
This breaks DebugAssert as well as REPL builds. Revert to appease the bots while i
look further.
This comes with a fix for a null pointer dereference in _typeByName()
that would pop with foreign classes that do not have a
NominalTypeDescriptor.
Also, I decided to back out part of the change for now, where the
NominalTypeDescriptor references an accessor function instead of a
pattern, since this broke LLDB, which reaches into the pattern to
get the generic cache.
Soon we will split off the generic cache from the pattern, and at
that time we can change the NominalTypeDescriptor to point at the
cache. But for now, let's avoid needless churn in LLDB by keeping
that part of the setup unchanged.

I reordered the CHECK statements in some tests to make them pass.
I tested this on Darwin and Linux.
Change conformance records to reference NominalTypeDescriptors instead of
metadata patterns for resilient or generic types.
For a resilient type, we don't know if the metadata is constant or not,
so we can't directly reference either constant metadata or the metadata
template.
Also, whereas previously NominalTypeDescriptors would point to the
metadata pattern, they now point to the metadata accessor function.
This allows the recently-added logic for instantiating concrete types
by name to continue working.
In turn, swift_initClassMetadata_UniversalStrategy() would reach into
the NominalTypeDescriptor to get the pattern out, so that its bump
allocator could be used to allocate ivar tables. Since the pattern is
no longer available this way, we have to pass it in as a parameter.
In the future, we will split off the read-write metadata cache entry
from the pattern; then swift_initClassMetadata_UniversalStrategy() can
just take a pointer to that, since it doesn't actually need anything
else from the pattern.
Since Clang doesn't guarantee alignment for function pointers, I had
to kill the cute trick that packed the NominalTypeKind into the low
bits of the relative pointer to the pattern; instead the kind is now
stored out of line. We could fix this by packing it with some other
field, or keep it this way in case we add new flags later.
Now that generic metadata is instantiated by calling accessor functions,
this change removes the last remaining place that metadata patterns were
referenced from outside the module they were defined in. Now, the layout
of the metadata pattern and the behavior of swift_getGenericMetadata()
is purely an implementation detail of generic metadata accessors.
This patch allows two previously-XFAIL'd tests to pass.
Incorporates a commit from master, where an extra overload for `+` on
Collection was removed.
Also fixes a minor bug where capacity was calculated incorrectly as
`rhs.count + rhs.underestimatedCount`.
This pull request broke the following tests on several build configurations

This reverts commit c223a3bf06, reversing
changes made to 5c2bb09b09.
Changes:
- Reverted commit reverting original SR-88 commit
- Removed mirror children helper collections and related code
- Rewrote some tests to keep them working properly
- Wrote two more tests for the three pointer APIs to ensure no crashes if created using a value > Int64.max
This reverts commit 8917eb0e5a.
This brings down StdlibUnittest build time to 90 seconds with either
a DebugAssert or a ReleaseAssert compiler.
The new library, StdlibCollectionTests, is only built when running
validation tests.
- Removed unnecessary #if guard
- Used IOReturn instead of Int32 return type
- Avoided private access control for overlays
- Added a test to ensure the type of the constants matches the return type of a IOKit function
Instead of directly emitting calls to swift_getGenericMetadata*() and
referencing metadata templates, call a metadata accessor function
corresponding to the UnboundGenericType of the NominalTypeDecl.
The body of this accessor forwards arguments to a runtime metadata
instantiation function, together with the template.
Also, move some code around, so that metadata accesses which are
only done as part of the body of a metadata accessor function are
handled separately in emitTypeMetadataAccessFunction().
Apart from protocol conformances, this means metadata templates are
no longer referenced from outside the module where they were defined.
The Generator interface is specialized for iteration and is often faster than indexing.
Using _initialize_to results in a ~10% speedup for Dictionary. For collections with more complex iteration state (such as search trees with O(log(n)) indexing), this leads to a complexity class improvement.
This requires a small change to the testsuite, because the generate() method of Defaulted*RangeReplaceableSlice called Array(self), which now leads to infinite recursion.
