runtime: segfaults in runtime.(*unwinder).next [1.24 backport]

[gopherbot]

@prattmic requested issue #73259 to be considered for backport to the next 1.24 minor release.

@gopherbot Please backport to 1.23 and 1.24. This issue causes random crashes when preempting functions with large stack frames on arm64.

Change https://go.dev/cl/689596 mentions this issue: [release-branch.go1.24] cmd/compile: for arm64 epilog, do SP increment with a single instruction

Closed by merging CL 689596 (commit 6e1c4529e4e00ab58572deceab74cc4057e6f0b6) to release-branch.go1.24.
