1bde11706e C++: Connect InitializeIndirection to UnmodeledDefinition
The IR generation for `InitializeIndirection` currently connects its load operand to the result of the corresponding `InitializeParameter` instruction. This isn't exactly wrong, but it doesn't fit the IR invariant of "All unmodeled uses consume `UnmodeledDefinition`". Our current code doesn't care, because we just throw away all of the existing def-use information, modeled or otherwise, when we build unaliased SSA. However, some upcoming SSA changes don't work correctly if this invariant is broken.

I've added the trivial IR generation change, along with a new sanity query.

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.

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.
