Fix PR 102908: wrongly removing null pointer loads
Just like PR 100382, here we have a DCE removing a
null pointer load which is needed still.
In this case, execute_fixup_cfg removes a store (correctly)
and then removes the null load (incorrectly) due to
not checking stmt_unremovable_because_of_non_call_eh_p.
This patch adds the check in the similar way as the patch
to fix PR 100382 did.
gcc/ChangeLog:
* tree-ssa-dce.c (simple_dce_from_worklist):
Check stmt_unremovable_because_of_non_call_eh_p also
before removing the statement.
