LLVM internally uses `uint64_t` for array size, but the corresponding C API (`LLVMArrayType`) uses `unsigned int` so ths value is truncated. Therefore rustc generates wrong type for fixed-sized large vector e.g. `[0 x i8]` for `[0u8, ..(1 << 32)]`. This patch adds `LLVMRustArrayType` function for `uint64_t` support.
