eBPF ISA specification requires high 32-bit cleared when only low 32-bit
sub-register is written. JIT back-ends must guarantee this semantics when
doing code-gen.
This patch complete unit tests for all of those insns that could be visible
to JIT back-ends and defining sub-registers, if JIT back-ends failed to
guarantee the mentioned semantics, these unit tests will fail.

It is better to centralize all sub-register zero extension checks into an
independent file.
This patch takes the first step to move existing sub-register zero
extension checks into subreg.c.
