mode-switching: Add note problem
optimize_mode_switching uses REG_DEAD notes to track register
liveness, but it failed to tell DF to calculate up-to-date notes.
Noticed by inspection. I don't have a testcase that fails
because of this.
gcc/
* mode-switching.cc (optimize_mode_switching): Call
df_note_add_problem.
