bpf/tests: Add tests of BPF_LDX and BPF_STX with small sizes
This patch adds a series of tests to verify the behavior of BPF_LDX and
BPF_STX with BPF_B//W sizes in isolation. In particular, it checks that
BPF_LDX zero-extendeds the result, and that BPF_STX does not overwrite
adjacent bytes in memory.
BPF_ST and operations on BPF_DW size are deemed to be sufficiently
tested by existing tests.
