tree-optimization/79334 - avoid PRE of possibly trapping array-ref

vn_reference_may_trap to fix hoisting of a possibly trapping
ARRAY_REF across a call that might not return.

* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Record
a type also for COMPONENT_REFs.
(vn_reference_may_trap): Check ARRAY_REF with constant index
against the array domain.

* gcc.dg/torture/pr79334-1.c: Likewise.
