@bronze1man requested issue #23889 to be considered for backport to the next 1.10 minor release.

@gopherbot please consider this for backport to 1.10. I just come cross this bug in my ios project.

Accepted because it's affecting all of arm64, not just iOS, it's a regression compared to 1.9.x. And it looks like a small, targeted fix for a serious problem.

The compiler now emits TBZ like instructions, but the assembler's
too-far-branch patch code didn't include that case. Add it.
