[PATCH] D156539: [Clang][CodeGen] `__builtin_alloca`s should care about address spaces too

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

We should probably write this code to work properly in case we add a target that makes `__builtin_alloca` return a pointer in the private address space.  Could you recover the target AS from the type of the expression instead of assuming `LangAS::Default`?
