The newly optimised CopyDataPropertiesWithExcludedProperties acceses the excluded properties directly on the stack, to avoid pushing them twice. This meant that we had to pass a stack pointer into the runtime, which we couldn't do directly because all arguments to runtime functions should be tagged. We tried to work around this by passing the stack pointer in a Foreign, but this violated the V8 sandbox. Fortunately, the stack pointer is aligned, so it looks like a Smi to the GC. So, we can pass it directly on the stack as a runtime argument but doing a bit of bitcasting.
