    asan: Fix ICE during instrumentation of returns_twice calls [PR112709]

    The following patch on top of the previously posted ubsan/gimple-iterat=
or
    one handles asan the same.  While the case of returning by hidden refer=
ence
    is handled differently because of the first recently posted asan patch,
    this deals with instrumentation of the aggregates returned in registers
    case as well as instrumentation of loads from aggregate memory in the
    function arguments of returns_twice calls.
