sim/h8300: avoid self assignment
There are two places in the h8300 simulator where we assign a variable
to itself. Clang gives a warning for this, which is converted into an
error by -Werror.
Silence the warning by removing the self assignments. As these
assignments were in a complex if/then/else tree, rather than try to
adjust all the conditions, I've just replaced the self assignments
with a comment and an empty statement.
