<h3>Log Message</h3>
<pre>Add a benchmark for string transcoding.
Rubber stamped by Saam Barati.
I wrote some code like this while working on
https://github.com/WebAssembly/design/pull/573. I thought I'd add it as a benchmark since
it stresses things that we may not have good bench coverage for.
* js/regress/script-tests/string-transcoding.js: Added.
(decodeUTF8):
(encodeUTF8):
(arraysEqual):
(arrayToString):
(setHeader):
(print):
(tryArray):
(doSteps):
* js/regress/string-transcoding-expected.txt: Added.
* js/regress/string-transcoding.html: Added.</pre>
