The testcase lays the way to proof that whatever PTA ends up putting in
the ESCAPED solution (which includes all globals) TBAA disambiguation
on these is invalid. This basically means that TBAA is nearly useless,

Nice testcase from PR38503:

Plan for attacking the problem:
1) Write a verifier that discovers illegal code motion.
1a) Each store and load is assigned a generation count.
1b) After code motion optimizations verify that out-of-order
