Richard Henderson e640545523 target/s390x: Simplify help_branch
Always use a tcg branch, instead of movcond.  The movcond
was not a bad idea before PER was added, but since then
we have either 2 or 3 actions to perform on each leg of
the branch, and multiple movcond is inefficient.

Reorder the taken branch to be fallthrough of the tcg branch.
