[Assignment Tracking][20/*] Account for assignment tracking in DSE
The Assignment Tracking debug-info feature is outlined in this RFC:
https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir
DeadStoreElimmination shortens stores that are shadowed by later stores such
that the overlapping part of the earlier store is omitted. Insert an unlinked
dbg.assign intrinsic with a variable fragment that describes the omitted part
to signal that that fragment of the variable has a stale value in memory.
