all: simplify multiple for loops
If a for loop has a simple condition and begins with a simple
"if x { break; }"; we can simply add "!x" to the loop's condition.
While at it, simplify a few assignments to use the common pattern
"x := staticDefault; if cond { x = otherValue(); }".
Finally, simplify a couple of var declarations.
