- Authentication-results: sourceware.org; auth=none
output_return and output_sibcall manually emit the instruction present in the
delay slot (if any) but fail to emit its source location information.
Tested on SPARC64/Linux, applied on the mainline.

* config/sparc/sparc.c (output_return): Output the source location of
the insn in the delay slot, if any.
(output_sibcall): Likewise.
