Add support for `__builtin_stack_address` builtin. The semantics match those of GCC's builtin with the same name. `__builtin_stack_address` returns the starting address of the stack region that may be used by called functions. It may or may not include the space used for on-stack arguments passed to a callee (See [GCC Bug/121013](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121013)). Fixes #82632.
