Piotr Sobczak ec10cb25d9 [InstCombine] Allow values with multiple users in SimplifyDemandedVectorElts ...

Summary:
Allow for ignoring the check for a single use in SimplifyDemandedVectorElts
to be able to simplify operands if DemandedElts is known to contain
the union of elements used by all users.
It is a responsibility of a caller of SimplifyDemandedVectorElts to
supply correct DemandedElts.

Simplify a series of extractelement instructions if only a subset of
elements is used.
