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.
