Anna Thomas 3ed40701a3 [RS4GC] Handle uses of extractelement for conversion from vector to scalar base 
As mentioned in the comments, extractelement is special
since we actually want a scalar base for that element we extracted from
the vector (i.e. not a vector base).
This same logic should apply to uses of the extractelement such as phis
and selects which have the same BDV as the extractelement.
Howeber, for these uses we conservatively mark the BDV state as
conflict, since setting the EE's new base BDV does not always dominate
these uses.

Added testcase showcases the problem where the BDV identification chokes
on the incorrect cast from vector to scalar for the phi use of
extractelement.

Tests-Run: make check, internal fuzzer testing
