Returns the current position of the C stack, for measuring how much of it has been consumed since an earlier call.

The stack pointer is read directly where the compiler or architecture allows it. Unlike __builtin_frame_address, that does not force the calling function to set up a frame pointer, which costs a register on targets that omit frame pointers by default (x86-64 at -O2), and unlike the address of a local it does not add a slot to the frame.
