[clang][bytecode] Tighten double-destroy check ( #129528 )
...
The instance pointer of the current function being the same as the one
we're destroying is only relevant if said function is also a destructor.

[clang][bytecode] Fix return value of array CXXNewExprs ( #127526 )

Just like with the __builtin_operator_new version, we need to point to
the first array element, not the array element itself.

[clang][bytecode] Support partial initializers for CXXNewExprs ( #126494 )
...
For `new A[N]{1,2,3}`, we need to allocate N elements of type A, and
initialize the first three with the given InitListExpr elements.
However, if N is larger than 3, we need to initialize the remaining
elements with the InitListExpr array filler.
Similarly, for `new A[N];`, we need to initilize all fields with the
constructor of A. The initializer type is a CXXConstructExpr of
IncompleteArrayType in this case, which we can't generally handle.

[clang][bytecode] Use std::allocator calls for Descriptor source ( #123900 )
...
... for the dynamic blocks created for operator new calls. This way we
get the type of memory allocated right. As a side-effect, the
diagnostics now point to the std::allocator calls, which is an
improvement.

[clang][bytecode] Check for memory leaks after destroying global scope ( #112868 )
...
The global scope we create when evaluating expressions might free some
of the dynamic memory allocations, so we can't check for memory leaks
before destroying it.
