re PR debug/50317 (missing DW_OP_GNU_implicit_pointer)
PR debug/50317
* tree-ssa.c (target_for_debug_bind): Also allow is_gimple_reg_type
vars that aren't referenced.
(tree-ssa-live.c (remove_unused_locals): Don't clear TREE_ADDRESSABLE
of unreferenced local vars.
* cfgexpand.c (expand_debug_expr): For DEBUG_IMPLICIT_PTR allow also
TREE_ADDRESSABLE vars that satisfy target_for_debug_bind.
