7cae774d9b benchmark: refactor to eliminate redeclared vars
In order to comply with linting rules used in the rest of the code base,
eliminate redeclared variables. A conservative approach is used so as to
avoid unintentional performance issues (for example, as might be seen in
some situations when using `let` instead of `var`).

46be1f4d0c querystring: improve escape() performance
This commit improves escape() performance by up to 15% with the
existing querystring-stringify benchmarks by reducing the number
of string concatentations. A potential deopt is also avoided by
making sure the index passed to charCodeAt() is within bounds.

301023b2b4 querystring: improve parse() performance
This commit improves parse() performance by ~20-200% with the various
querystring-parse benchmarks.

Some optimization strategies used in this commit include:
* Combining multiple searches (for '&', '=', and '+') on the same
   string into a single loop
* Avoiding string.split()
* Minimizing creation of temporary strings
* Avoiding string decoding if no encoded bytes were found and the
   default string decoder is being used
