Andrew Trick 7dc21d8c0e Fix an overly general check in SimplifyIndvar to handle useless phi cycles.

The right way to check for a binary operation is
cast<BinaryOperator>. The original check: cast<Instruction> &&
numOperands() == 2 would match phi "instructions", leading to an
infinite loop in extreme corner case: a useless phi with operands
[self, constant] that prior optimization passes failed to remove,
being used in the loop by another useless phi, in turn being used by an
lshr or udiv.

Fixes PR11350: runaway iteration assertion.

Fix bug in RefCountedBase/RefCountedBaseVPTR where the reference count was accidentally copied as part of the copy constructor. This could result in objects getting leaked because there reference count was too high.
