[LAA] RtCheck on pointers of different address spaces.
...hese pointers. (If you revert this patch locally, the testcase will compile successfully).
The address-space validation (given below) prevented the RT check for these pointers earlier which I expected even to get triggered with the upstream compiler today.
But it didn’t occur as they have the same DependenceSetId value. (The DependenceSetId starts from 1 for each Alias Set and hence pointers of
different AS can have the same Id. If it is intended, I am not sure that the early continue here, only based on the DependenceSetId, handled all cases)

[LAA] RtCheck on pointers of different address spaces.
...le the pointers 1 & 2 belong to one Alias Set (AS1), pointers 3 & 4 belong to a different set (AS2). It is because, the Global Alias Analysis found there is no alias between these two sets of pointers.
The crash occurs with the pointers 1 & 4 which are from AS1 and AS2 respectively.
The DependenceSetId will be reset to 1 before processing a new AS and the pointers in question, ended up having the same DependenceSetId (1), though they are from different AS.
