// Test TBAA tags assignment for access off the fir.declare
// placed in the middle of the routine (e.g. a temporary).
// Original example:
// module m
// type t
// real :: x
// end type t
// contains
// subroutine bar(this)
// class(t), intent(out) :: this
// this%x = 1.0
// end subroutine bar
// function foo() result(res)
// type(t) :: res
// call bar(res)
// end function foo
// subroutine test(arg)
// type(t) :: var
// var = foo()
// arg = var%x
// end subroutine test
// end module m
//
// The calls were manually inlined in FIR with fir.save_result's
// destination operand being used instead of the temporary
// alloca of the result inside foo. Runtime calls were removed
// to reduce the test.
// The temporary function result fir.declare is then dominated
// by fir.dummy_scope of the foo function. If we use this scope
// to assign the TBAA local-alloc tag to the accesses of
// the temporary, then it won't conflict with the TBAA dummy tag
// assigned to the accesses of this argument of bar.
// That would be incorrect, because they access the same memory.
// Check that the local-alloc tag is placed into the outermost
// scope's TBAA tree.
