dd322be238 C++: Remove noise from argHasPostUpdate check 
This consistency check seems to have value for AST data flow, but I've
disabled it on the IR for now.

This commit also includes two unrelated changes that seem to fix a
semantic merge conflict.

due to https://github.com/Semmle/ql/pull/3123 and possibly

8f419d1676 C++: Fix conflated-memory sanity query 
I had included `InitializeNonLocal` in the recursion because it made
everything look better in the presence of a bug that's since been fixed.
Taking it out means the sanity test is again aligned with the old
`isChiForAllAliasedMemory`.

c5ac357bfc C++/C#: Fix bad overlap sanity failures 
`Instruction.getDefinitionOverlap()` depends on `SSAConstruction::getMemoryOperandDefinition()`, which in turn depends on `SSAConstruction::hasMemoryOperandDefinition()`. When the definition in question came from a `Chi` instruction, `hasMemoryOperandDefinition()` incorrectly bound `overlap` to the overlap relationship between the original (non-`Chi`) instruction and the use. The fix is to make use of the `actualDefLocation` parameter to `getDefinitionOrChiInstruction()`, which specifies the location for the result of the `Chi` in that case.

Dave Bartolomeo
a2741da8e2 C++/C#: Add sanity test for invalid overlap from getDefinitionOverlap() 
The result of `getDefinitionOverlap()` should never be `MayPartiallyOverlap`, because if that were the case, we should have inserted as `Chi` instruction and hooked the definition up to that instead.

There are quite a few existing failures.
