With bytecode flushing and lazy feedback allocation, we need to call %PrepareForOptimization before we call %OptimizeFunctionOnNextCall, ideally after declaring the function.

Due to hoisting, the value of a 'var'-declared variable may actually change even if the code contains only the "initial" assignment, namely when that assignment occurs inside a loop. For example: let i = 10; do { var x = i } while (i--): As a simple and very conservative approximation of this, we explicitly mark as maybe-assigned any non-lexical variable whose "declaration" does not syntactically occur in the function scope. (In the example above, it occurs in a block scope.) BUG=v8:5636 Review-Url: https://codereview.chromium.org/2673403003 Cr-Commit-Position: refs/heads/master@{#42989}
