// Consider a case of potentially skipping probing a page on ARM64.
// 1. Have a function with a frame just under a page size, so it doesn't
// require a probing loop. Most of the frame size is outgoing argument
// space, which is untouched.
// 2. Call a function that doesn't force touching the outgoing argument
// space.
// 3. The called function has a frame size <=504 bytes with no outgoing
// arguments. Then, the first page touch will be at [sp-504] when
// FP/LR is saved, and SP is set.
