Make the Benchmark button look more like a button

[juanmendes]

I think the Benchmark button is not intuitive enough. I often need to think a few times before realizing it's a button. I use it at https://stackoverflow.com/questions/51185/are-javascript-strings-immutable-do-i-need-a-string-builder-in-javascript/4717855#4717855

Two (not well-though-out) suggestions:

• Making it have a border and be more 3D looking like a standard button.
• Having a run ▶️ icon
  ▶️ Benchmark

fixed, plus there's a new feature - groups, i've updated your stackoverflow answer (so you can see how that could be done) and benchmark results. you can benchmark for safari, run 5 times for the best result. so you can now remove your screenshots, use markdown copy the next times, thanks

Will update the answer with the copied markdown!

@juanmendes added auto estimation of cycles and number of times to run benchmarks, updated your answer. if you don't set the cycles they are calculated automatically for each solution, looks cool.
btw Firefox get worse with the new update:

Cycles: 50000 / Firefox/117
---------------------------------------------------------------
Same string 'Hot diggity dizzle'
    string concatenation   1.0x  |  176   180   187   198   203
    array push & join      5.2x  |  911  1082  1143  1147  1159
Random strings

Tested Chrome 117 with auto estimation of cycles = the same results, so seems the estimation works ok
