[PATCH 0/3] x86: branch handling adjustments

[Jan Beulich]

In the middle of addressing PR gas/24546 I've run into an issue
with a pre-existing test case, pointing out problems to be fixed
prior to being able to actually deal with the issues reported
there. In turn I've then noticed further issues, which the latter
two patches deal with.

1: x86-64: fix Intel64 handling of branch with data16 prefix
2: x86-64: correct / adjust prefix emission
3: x86: adjust ignored prefix warning for branches
