[ree] PR rtl-optimization/78038: Handle global register dataflow definitions in ree
PR rtl-optimization/78038
* ree.c (get_defs): Return NULL if a defining insn for REG cannot
be deduced to set REG through the RTL structure.
(make_defs_and_copies_lists): Return false on a failing get_defs call.
* gcc.target/aarch64/pr78038.c: New test.
