Ron Lieberman 9bcdd80b66 [Hexagon] Check vector elements for equivalence in the HexagonVectorLoopCarriedReuse pass 
If the two instructions being compared for equivalence have corresponding operands
    that are integer constants, then check their values to determine equivalence.

Galina Kistanova 1c6f0bb63e Reverted r313993. 
This patch produces a crash and hexagon_vector_loop_carried_reuse_constant.ll test fails on Windows (llvm-clang-x86_64-expensive-checks-win build bot).

Pranav Bhandarkar 931d0b7aff Enable the reuse of values computed in a previous loop iteration. 
This patch adds a pass that removes the computation of provably redundant
expressions that have been computed earlier in a previous iteration. It
relies on the use of PHIs to identify loop carried dependences.

This is scalar replacement for vector types.
