David Stenberg 11ef6e19fe Allow null-valued function operands in getCalledFunction() ... Summary: Change the dynamic cast in CallBase::getCalledFunction() to allow null-valued function operands. This patch fixes a crash that occurred when a funtion operand of a call instruction was dropped, and later on a metadata-carrying instruction was printed out. When allocating the metadata slot numbers, getCalledFunction() would be invoked on the call with the dropped operand, resulting in a failed non-null assertion in isa<>. This fixes PR38924, in which a printout in DBCE crashed due to this. This aligns getCalledFunction() with getCalledValue(), as the latter allows the operand to be null.
