llvm: default init of arrays & structs
Linearization of arrays & structs default initialization is done
as if these objects would be an integer as large as the object.
This integer is then simply zero-initialized.
(This may be objectionable and will be done differently).
However, sparse-llvm is not ready to handle this situation where
a non-scalar is initialized with a scalar value.
Workaround this by using LLVMConstNull() when possible.
