Abstract IR generation of array cookies into the C++ ABI class and
...
implement ARM array cookies. Also fix a few unfortunate bugs:
- throwing dtors in deletes prevented the allocation from being deleted
- adding the cookie to the new[] size was not being considered for
overflow (and, more seriously, was screwing up the earlier checks)
- deleting an array via a pointer to array of class type was not
causing any destructors to be run and was passing the unadjusted
pointer to the deallocator
- lots of address-space problems, in case anyone wants to support
free store in a variant address space :)

- This is designed to make it obvious that %clang_cc1 is a "test variable"

can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
