Jun Bum Lim 44c58d35c1 Re-commit : [LICM] Allow sinking when foldable in loop ...

This recommits r320823 reverted due to the test failure in sink-foldable.ll and
an unused variable. Added "REQUIRES: aarch64-registered-target" in the test
and removed unused variable.

Original commit message:

  Continue trying to sink an instruction if its users in the loop is foldable.
  This will allow the instruction to be folded in the loop by decoupling it from
  the user outside of the loop.
