Add two tests validating that verifier's precision backtracking logic handles BPF_ST_MEM instructions that produce fake register spill into register slot. This is happening when non-zero constant is written directly to a slot, e.g., *(u64 *)(r10 -8) = 123. Add both full 64-bit register spill, as well as 32-bit "sub-spill".
