d829a02514 Add a new GetAddressOfBaseClass overload that takes a base path and. Use it for derived-to-base casts.

914af2182b Handle compound assignment expressions (i += j) as lvalues, which is 
permitted in C++ but not in C. Fixes PR6900. Clang can now handle all
of Boost.Lambda's regression tests.

2e6567ae60 Call PerformCopyInitialization to properly initialize the exception temporary 
in a throw expression.  Use EmitAnyExprToMem to emit the throw expression,
which magically elides the final copy-constructor call (which raises a new
strict-compliance bug, but baby steps).  Give __cxa_throw a destructor pointer
if the exception type has a non-trivial destructor.

bf814c79b6 I failed to notice that my last patch wasn't doing as much as it could 
because EmitBranch actually clears the insert point.  This version
actually accomplishes what I initially wanted.

2188696d98 Miscellaneous codegen cleanups. Mostly, don't create new basic blocks 
just to save the current insertion state!  This change significantly
simplifies the IR CFG in exceptions code.

6a0227df49 Fix a bug which triggered the assertion I added yesterday. Basically, when we initialize the vtable pointer for a virtual base, and there was another path from the most derived class to another base with the same class type, we would use the wrong base.

74eab715ae More improvements to setting the vtable pointer. We now no longer set the vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors.

fc83aa04db Unconditionally support block introspection data in a new field at the end 
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations: 
1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

b81884d347 More refactoring around constructor/destructor code generation. 
Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.

347132b32f IRgen optimization: cache the value of 'this' and 'vtt' instead of 
repeatedly reloading from an alloca.  We still need to create the alloca
for debug info purposes (although we currently create it in all cases
because of some abstraction boundaries that're hard to break down).

6ce747220a When emitting complete destructors for classes with virtual bases, compute 
the offset to the virtual bases statically inside of relying on the virtual
base offsets in the object's vtable(s).  This is both more efficient and
sound against the destructor's manipulation of the vtables.

Also extract a few helper routines.

Oh and we seem to pass all tests with an optimized clang now.

a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. 
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!
