Cherry Mui fa42da156a [release-branch.go1.20] cmd/link: use label symbols for Duff's devices on darwin/arm64 
On darwin, the external linker generally supports CALL relocations
with addend. One exception is that for a very large binary when it
decides to insert a trampoline, instead of applying the addend to
the call target (in the trampoline), it applies the addend to the
CALL instruction in the caller, i.e. generating a call to
trampoline+addend, which is not the correct address and usually
points to unreloated functions.

To work around this, we use label symbols so the CALL is targeting
a label symbol without addend. To make things simple we always use
label symbols for CALLs with addend (in external linking mode on
darwin/arm64), even for small binaries.

Updates #58935.
Fixes #58954.
