Hi!
ggc_mark_rtx_children does not mark NOTE_INSN_EXPECTED_VALUE's rtx argument,
I've seen it when compiling sparc 32bit glibc with 64bit gcc, where
NOTE_EXPECTED_VALUE argument contained random garbage.
IMHO NOTE_INSN_DELETED_LABEL needs similar treatment.
Ok to commit?

* gcc-common.c (ggc_mark_rtx_children): Mark NOTE_EXPECTED_VALUE
from NOTE_INSN_EXPECTED_VALUE notes and NOTE_SOURCE_FILE from
NOTE_INSN_DELETED_LABEL.
