[BitcodeReader] Check if we can create a null constant for type.
We cannot create null constants for certain types, e.g. VoidTy,
FunctionTy or LabelTy. getNullValue asserts if we pass in an
unsupported type. We should also check for opaque types, but I'm not
sure how.
This fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14795.
