re PR sanitizer/81111 (Cannot build libstdc++ with -fsanitize=undefined)

PR sanitizer/81111
* ubsan.c (ubsan_encode_value): If current_function_decl is NULL,
use create_tmp_var_raw instead of create_tmp_var, mark it addressable
just by setting TREE_ADDRESSABLE on the result and use a TARGET_EXPR.

* g++.dg/ubsan/pr81111.C: New test.
