As outlined in the BZ simplify_logical_relational_operation does not validate
that the comparison code it selects is ultimately valid for the mode of the
comparison.
So we could have something like:

Which it happily turns into

Which is not valid for int

This patch fixes two issues:
(a) The target size is the pointer size and
host size is the variable size itself; thus, it fails often.
(b) Only the host variable has the link-var bit flip, hence,
we need to check this one not the target var's size.
