Hans-Kristian Arntzen 03d93abc1a Deal with case where a variable is dominated by inner part of a loop.
There is a risk that we try to preserve a loop variable through multiple
iterations, even though the dominating block is inside a loop.

Fix this by analyzing if a block starts off by writing to a variable. In
that case, there cannot be any preservation going on. If we don't, pretend the
loop header is reading the variable, which moves the variable to an
appropriate scope.
