llvm: fixup elem_count argument of ZigLLVMCreateDebugArrayType to be i64

The signature is `getOrCreateSubrange(int64_t  Lo, int64_t  Count)`, so this updates the bindings to match.

This fixes a crash in `lowerDebugTypeImpl` when analyzing slices that have a length of 2^32 or
larger (up to `2^64 >> 3`, which still crashes, because above that the array size in bits overflows u64).
