Add User::growHungoffUses and use it to grow the hung off uses. NFC.

PhiNode, SwitchInst, LandingPad and IndirectBr all had virtually identical
logic for growing the hung off uses.
Move it to User so that they can all call a single shared implementation.

Their destructors were all empty after this change and were deleted.  They all
have virtual clone_impl methods which can be used as vtable anchors.

Reviewed by Duncan Exon Smith.
