bfin.c (np_check_regno, [...]): New static variables.
* config/bfin/bfin.c (np_check_regno, np_after_branch): New static
variables.
(note_np_check_stores): New function.
(harmless_null_pointer_p): New function.
(trapping_loads_p): New args NP_REG and AFTER_NP_BRANCH. Callers
changed. Take into account whether we're in the shadow of a condjump
that tested NP_REG for NULL.
Lose all code that tested for SEQUENCEs.
(workaround_speculation): Avoid inserting NOPs for loads that are
either always executed or a NULL pointer.
