The enclosed change fixes PR 14838. It makes get_first_nonnote_insn and get_last_nonnote_insn more conservative in that they no longer assume that the first/last insn is always a note insn.
The only users of these two functions are pa.c and avr.c.
Tested on hppa-unknown-linux-gnu, 3.3, 3.4 and 4.0 branches with no regressions.
Ok for 3.3, 3.4 and main?
