Bill Wendling e106c34817 LLVM doesn't always optimize away the four loads from this:
(__m128){ p[0], p[1], p[2], p[3] }

which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

hope).

Anders Carlsson cc53197903 Don't emit complete constructors for abstract classes. Also, don't emit
complete destructors for abstract classes unless the destructor is virtual
and thus needs to be in the vtable.

Douglas Gregor 2d1c055eba In C++, allow us to emit a global as 'constant' even if it has class
type, so long as it is known to have a constant initializer and the
class type is a POD class. Fixes <rdar://problem/9306265>.

Alexis Hunt 4a8ea1092a Modify some deleted function methods to better reflect reality:
- New isDefined() function checks for deletedness
 - isThisDeclarationADefinition checks for deletedness
 - New doesThisDeclarationHaveABody() does what
   isThisDeclarationADefinition() used to do
 - The IsDeleted bit is not propagated across redeclarations
 - isDeleted() now checks the canoncial declaration
 - New isDeletedAsWritten() does what it says on the tin.
 - isUserProvided() now correct (thanks Richard!)

This fixes the bug that we weren't catching

void foo() = delete;
void foo() {}

as being a redefinition.

Eli Friedman 409943efcb Don't emit nsw flags for vector operations; there's basically no benefit, and a lot of downside (like PR9850, which is about clang's xmmintrin.h making an unexpected transformation on an expression involving _mm_add_epi32).

Eli Friedman 49a94b1c7c Add an implementation of thunks for varargs methods. The implementation is a bit messy, but it is correct as long as the method in question doesn't use indirect gotos.

Bill Wendling f7d4598b74 Pack ivar offsets together.
Ivar offsets for synthesized ivars are wrong, which could end up with a large
number of dirty pages because of ivar fixups at runtime. When we pack all of the
synthesized ivars into the same section, it limits the number of dirty pages
created. Place them in the "__DATA,__objc_ivar" section.

Alexis Hunt 9d47faf686 Ensure that destructors are properly inovked when an exception leaves
the body of a delegating constructor call.

This means that the delegating constructor implementation should be
complete and correct, though there are some rough edges (diagnostic
quality with the cycle detection and using a deleted destructor).

Nick Lewycky fc49f72b58 Remove unused variable spotted by GCC.
Devang, can we remove this call entirely? If I try that, "make check" passes
but the call has a side-effect of ensuring that the block's context exists in
the debug info. getContextDescriptor() is used in a void context for that side-
effect elsewhere in this file. Please take a look!

Alexis Hunt 61bc173784 Fully implement delegating constructors!
As far as I know, this implementation is complete but might be missing a
few optimizations. Exceptions and virtual bases are handled correctly.

Because I'm an optimist, the web page has appropriately been updated. If
I'm wrong, feel free to downgrade its support categories.
