Also, say "guard-offset pages" rather than just "guard pages" to describe the region of a heap which is never accessible and which exists to support optimizations for heap accesses with offsets. And, introduce a `Uimm64` immediate type, and make all heap fields use `Uimm64` instead of `Imm64` since they really are unsigned.
