("[PATCH] tcg: `reachable_code_pass()` remove empty else-branch")

Anton has probably seen this already but his patch now has conflicts
with master.  Rather than a while loop looking back across labels, let's
fold all adjacent labels into a single label, at which point the
current branch-to-next optimization works as is.

Perhaps I missed it, but I didn't see how to reproduce the issue
being resolved by the hexagon front end?  So I haven't this trigger,
but it passes the testsuite.  :-)
