4b4beb2fe7 Fix PR11073 by adding the argument type information to the decl we construct 
for the function type. Update a testcase accordingly.

47f9a73f51 c++: support gcc's application of weak attribute on 
class declaration which forces any such class and any 
class that inherits from such a class to have their 
typeinfo symbols be marked as weak.

0710e551ef Record layout requires not just a definition, but a complete 
definition.  Assert this.  Change IR generation to not try to
aggressively emit the IR translation of a record during its
own definition.  Fixes PR10912.

f0724e8e06 Throw the switch to convert clang to the new exception handling model! 
This model uses the 'landingpad' instruction, which is pinned to the top of the
landing pad. (A landing pad is defined as the destination of the unwind branch
of an invoke instruction.) All of the information needed to generate the correct
exception handling metadata during code generation is encoded into the
landingpad instruction.

The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic
call. It's lowered in much the same way as the intrinsic is.

20104048be PR10304: Do not call destructors for data members from union destructors. Prior to C++11, this

be called.

e0e9630e07 When extracting the callee declaration from a call expression, be sure 
to look through SubstNonTypeTemplateParmExprs. Then, update the IR
generation of CallExprs to actually use CallExpr::getCalleeDecl()
rather than attempting to mimick its behavior (badly).

154a2fd3cb Be sure to emit lvalue-to-rvalue casts for loads from x-values. 
Doing this happens to disrupt the pattern that ARC was looking for
for move optimizations, so we need to fix that simultaneously.

29ad95b232 The lvalue-to-rvalue on structs in C++ is actually part

46759f4f46 Since the 'is aliased' bit is critical for correctness in C++, it

temporary was being passed as potentially-aliased memory.

a5efa7386a Track whether an AggValueSlot is potentially aliased, and do not 
emit call results into potentially aliased slots.  This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value.  It also brings us into compliance with
the x86-64 ABI.

4e6bd3955f Remove this test. It requires C++ standard library headers, which we'd 
like to avoid within the Clang test suite, it doesn't verify the output
at all so it only servers as a test that Clang doesn't crash, and
finally all it does is declare a function that returns a vector and call
it. Probably the biggest thing being tested here is Clang's parsing of
the vector template, and we have lots of good template parsing tests. We
don't need another in codegen.
