This adds the benchmarks suite to the deopt fuzzer and removes the obsolete deopt configs, which since a while are part of the num-fuzz configs.

This is the implementation of crrev.com/c/866721 for mips and mips64. Drive-by change: I made the slot index calculation on mips the same as on mips64. Original description: At the moment the slot index is encoded in the opcode. This, however, sets an upper limit the slot index which is lower than what we want to have (i.e. < 512). With this change we pass the slot index as an immediate operand, which does not impose limits on the value it contains.

Until now, String.prototype.{trimLeft,trimRight} were non-standard language extensions, required for Web compatibility. The proposal at https://github.com/tc39/proposal-string-left-right-trim standardizes this functionality as String.prototype.{trimStart,trimEnd}, and defines String.prototype.{trimLeft,trimRight} as aliases for backwards compatibility. This patch implements that proposal behind the --harmony-string-trimming flag.

This avoids the call to the StringCharCodeAt builtin from within TurboFan optimized code and instead emits a loop that does the character load. This (together with previously reverted CL to the JSCallReducer) almost completely recovers the performance regression caused when we shipped TurboFan. Without untrusted code mitigations the benchmark goes from 580ms to roughly 490ms, and with the patch to the JSCallReducer the time goes down to 280ms, which is very close to what we had with Crankshaft. This also renames the LoadFromString helper method in the EffectControlLinearizer to LoadFromSeqString to make it clear what it does.

It took me a while to understand that the {index} is actually a signature index. This CL changes the name to {sig_index} to make this more clear. Drive-by: Fix a CHECK to check the canonical signature index instead of the original index. This ensures that there is a canonical signature index in the signature map. Drive-by^2: Un-templatize a method.
