[Bug rtl-optimization/43156] New: [4.5 Regression] SPU-elf ICEs on simple programs

[pinskia at gcc dot gnu dot org]

As mentioned here:
http://gcc.gnu.org/ml/gcc-patches/2010-02/msg00780.html
Just building a simple: int main(void) { return 0; }
ICEs at -O1 or -O2.  This ICEs as we call add_reg_note with an insn note:
(note 21 12 22 2 NOTE_INSN_DELETED)
And REG_NOTES causes the next insn rtx gets modified for some reason.
