Summary: Check if the parent basic block and caller exists before calling CS.getCaller when constant folding strip.invariant.group instrinsic. This avoids a crash when the function containing the intrinsic is being inlined. The instruction is checked for any simplifiction but has not yet been added to a basic block.
