1c036841 - [clang][analysis] Fix flaky clang/test/Analysis/live-stmts.cpp test (2nd attempt) (#127406)

[clang][analysis] Fix flaky clang/test/Analysis/live-stmts.cpp test (2nd attempt) (#127406) In my previous attempt (#126913) of fixing the flaky case was on a good track when I used the begin locations as a stable ordering. However, I forgot to consider the case when the begin locations are the same among the Exprs. In an `EXPENSIVE_CHECKS` build, arrays are randomly shuffled prior to sorting them. This exposed the flaky behavior much more often basically breaking the "stability" of the vector - as it should. Because of this, I had to revert the previous fix attempt in #127034. To fix this, I use this time `Expr::getID` for a stable ID for an Expr. Hopefully fixes #126619 Hopefully fixes #126804 (cherry picked from commit f378e52ed3c6f8da4973f97f1ef043c2eb0da721)
