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.

Rename -constructors test to just -structors as in fact it tests dtors too. Also, fix a minor typo in the test.
