In my fix for PR 119318 I put mask calculation in
ipcp_bits_lattice::meet_with_1 above a final fix to value so that all
the bits in the value which are meaningless according to mask have
value zero, which has tripped a validator in PR 119803. This patch
fixes that by moving the adjustment down.
Even thought the fix for PR 119318 did a similar thing in
ipcp_bits_lattice::meet_with, the same is not necessary because that
code path then feeds the new value and mask to
ipcp_bits_lattice::set_to_constant which does the final adjustment
correctly.
In both places, however, Jakup proposed a better way of calculating
cap_mask and so I have changed it accordingly.

PR ipa/119803
* ipa-cp.cc (ipcp_bits_lattice::meet_with_1): Move m_value adjustmed
according to m_mask below the adjustment of the latter according to
cap_mask. Optimize the calculation of cap_mask a bit.

bit.
