cmd/link: detect trampoline of deferreturn call The runtime needs to find the PC of the deferreturn call in a few places. So for functions that have defer, we record the PC of deferreturn call in its funcdata. For very large binaries, the deferreturn call could be made through a trampoline. The current code of finding deferreturn PC fails in this case. This CL handles the trampoline as well. Fixes #39049.
