303249c4 - [flang][StackArrays] track pointers through fir.convert (#121919)

[flang][StackArrays] track pointers through fir.convert (#121919) This does add a little computational complexity because now every freemem operation has to be tested for every allocation. This could be improved with some more memoisation but I think it is easier to read this way. Let me know if you would prefer me to change this to pre-compute the normalised addresses each freemem operation is using. Weirdly, this change resulted in a verifier failure for the fir.declare in the previous test case. Maybe it was previously removed as dead code and now it isn't. Anyway I fixed that too.
