Simon Tatham 45e4fbf207 Fix handling of large RHS in mp_add_integer_into. ...

While looking over the code for other reasons, I happened to notice
that the internal function mp_add_masked_integer_into was using a
totally wrong condition to check whether it was about to do an
out-of-range right shift: it was comparing a shift count measured in
bits against BIGNUM_INT_BYTES.

The resulting bug hasn't shown up in the code so far, which I assume
is just because no caller is passing any RHS to mp_add_integer_into
bigger than about 1 or 2. And it doesn't show up in the test suite
because I hadn't tested those functions. Now I am testing them, and
the newly added test fails when built for 16-bit BignumInt if you back
out the actual fix in this commit.
