Arnold Schwaighofer 67e3d27fd9 Copy-on-write existential performance work (#8369) ...

* IRGen: Change c-o-w existential implementation functions

* initialzeBufferWith(Copy|Take)OfBuffer value witness implementation for cow existentials

Implement and use initialzeBufferWith(Copy|Take)OfBuffer value witnesses for
copy-on-write existentials.

Before we used a free standing function but the overhead of doing so was
noticable (~20-30%) on micro benchmarks.

* IRGen: Use common getCopyOutOfLineBoxPointerFunction

* Add a runtime function to conditionally make a box unique

* Fix compilation of HeapObject.cpp on i386

* Fix IRGen test case

* Fix test case for i386
