re PR sanitizer/81715 (asan-stack=1 redzone allocation is too inflexible)

PR sanitizer/81715
* tree-inline.c (expand_call_inline): Emit clobber stmts for
VAR_DECLs to which addressable non-volatile parameters are mapped
and for id->retvar after the return value assignment.  Clear
id->retval and id->retbnd after inlining.

* g++.dg/tree-ssa/pr8781.C (noop): Change argument type from
const predicate to const predicate & to avoid UB.
* g++.dg/opt/pr81715.C: New test.
