*%(basename)s:6: SyntaxError: Identifier 'x' has already been declared
  let x
      ^
SyntaxError: Identifier 'x' has already been declared
[parser] Change how conflicting param and let in body declarations are detected Now we just check for each variable declared in the parameter scope whether it occurs as a lexical variable in the body scope. This way the preparser will also identify them.

[parser] Declare variables through ExpressionScope Use variable tracking from ExpressionScopes rather than the PatternRewriter and PreParserExpression::variables_ to declare variables. We only figure out that variables are non-simple parameters once we see the first non-simple parameter. This still uses the pattern rewriter to make variables non-simple (kLet instead of kVar).
