[Bug rtl-optimization/19462] New: generating return insns while current_function_epilogue_delay_list nonempty

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Similar to PR target/7042, this bug is about reorg generating
a return insn while current_function_epilogue_delay_list.
The test-case is newlib/libc/string/wcscspn.c:1.1, which will
be entered in the test-suite (including copyright/license note)
with modified data-types to avoid included files.

Like PR target/7042, this should only affect targets with
ELIGIBLE_FOR_EPILOGUE_DELAY

Noticed thanks to the sanity check in the CRIS port
introduced with the fix for PR target/7042.

The error looks like this, cutnpasted:
