Assert that we do not try to memcpy a non-POD class type in C++. This
particular issue was the cause of the Boost.Interprocess failures, and
in general will lead to horrendous, hard-to-diagnose miscompiles. The
assertion itself has survives self-host and a full Boost build, so we
are close to eradicating this problem in C++.

Note that the assertion is *not* turned on for Objective-C++, where we
still have problems with introducing memcpy's of non-POD class
types. That part of the assertion will go away as soon as we fix the
known issues in Objective-C++.

Remove an unused function.

If we're generating code to create a pointer-to-member function
aggregate and the result of the aggregate is unused, bail out
early. Fixes PR7027.

When computing the address of a virtual member function pointer, use the pointer width instead of hardcoding for 64-bit.

Fix PR6648 by not creating a temporary with the type of a
CXXExprWithTemporaries.

Not emitting the expression as an aggregate might be the right thing to do,
but is orthogonal. Emitting it as an scalar expression will still try to
create a temporary for the incomplete type of the CXXExprWithTemporaries and
fail.

add a codegen hack to work around an AST bug, allowing us to compile the

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!
