  StackProtector: use isInTailCallPosition to verify tail call position (#68997)

The issue is caused by [D133860](https://reviews.llvm.org/D133860).
The guard would be inserted in wrong place in some cases, like the test
case showed below.
This patch fixed the issue by using `isInTailCallPosition()` to verify
whether the tail call is in right position.
