Anna Thomas eb282be9f8 [RS4GC] Fix algorithm to avoid setting vector BDV for scalar derived pointer"" 
This is relanding of rGbb308b020522420413c7d3f2989a88f2fc423c56 after
speculatively fixing buildbot lit test failure which was seen on two
bots (I cannot reproduce the lit test failure locally either).

[RS4GC] Fix algorithm to avoid setting vector BDV for scalar derived
pointer

Summary:
This is a more general fix to 59029b9eef (D75704).
This patch does the following:

updates isKnownBaseValue to account for base pointer and
derived pointer having differing types.

This inturn allows us to populate the
lattice (States) for such derived pointers.

It also updates all states where the base and derived pointers have
differing types (vector versus scalar) and conservatively marks these
states as conflictcs.
Note that in 59029b9eef, we were just fixing existing lattice values
and that too, only for uses of extractelement.
