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. 2019-06-06 09:10:39 +00:00			`#version 310 es`
