size_t on Darwin AAPCS targets is "unsigned long". <rdar://problem/14136459>

Some embedded targets use ARM's AAPCS with iOS header files that define size_t
as unsigned long, which conflicts with the usual AAPCS definition of size_t
as unsigned int.

Remove option emitter from clang-tblgen

The CMake build was still using it because I forgot to s/CLANG/LLVM/ in
the tablegen() call.  The Makefile build is already using llvm-tblgen.

CodeGen: Have 'this'-returning constructors and destructors to take advantage of the new backend 'returned' attribute.

The backend will now use the generic 'returned' attribute to form tail calls where possible, as well as avoid save-restores of 'this' in some cases (specifically the cases that matter for the ARM C++ ABI).

This patch also reverts a prior front-end only partial implementation of these optimizations, since it's no longer required.
