histogram rval string length
Out of 205132 calls of
JSString * JS_FASTCALL
js_ConcatStrings(JSContext *cx, JSString *left, JSString *right),
138609 times the rval string has length 1. rel: 67.570637%.
A benchmark builds a huge string by just adding one all the time. (calling concatStrings for 21845 times)
Maybe a candidate for optimization?
(In the histogram, length 64 also includes all bigger strings.)
