The CheckedInt32Mod lowering in the EffectControlLinearizer wasn't playing well with subsequent optimizations in the MachineOperatorReducer especially due to the use of Int32Mod, which introduces another (floating) diamond in the MachineOperatorReducer. Switching to Uint32Mod and explicit sign handling fixes the problem, plus we also do the mask trick in the case where the left hand side is negative now. With this change the performance on the benchmark mentioned in the bug report goes from console.timeEnd: binary, 1872.346000 console.timeEnd: modulo, 5967.464000 console.timeEnd: binary, 6006.789000 console.timeEnd: modulo, 6293.496000 console.timeEnd: binary, 5969.264000 console.timeEnd: modulo, 6291.874000 to console.timeEnd: binary, 1876.464000 console.timeEnd: modulo, 5846.643000 console.timeEnd: binary, 5962.545000 console.timeEnd: modulo, 5972.639000 console.timeEnd: binary, 5958.221000 console.timeEnd: modulo, 5973.171000 so even the peak performance of the modulus is now mostly the same as the binary bitwise and.

The RegExp replace implementation is a bit of a mess. Here, we first try to handle parts of RegExp.p.exec, and then call directly into the raw irregexp code (skipping RegExp.p.exec). We got parts of this wrong: when lastIndex > string.length and the regexp instance is sticky, two things should happen. 1. The match should fail, and 2. lastIndex should be reset to 0. On the fast path, we did the latter but not the former, instead running exec with a lastIndex of 0. This CL omits the irregexp call in this case, and defaults to a failed match instead.

Use CheckBounds and reduce the number of checks required to sanitize the indices for DataView accesses in optimized code. Also constant-fold the [[ByteLength]] if the DataView is a known compile-time constant (similar to what we do for TypedArrays already). This further improves performance of DataViews by 2-7% depending on the exact test case. With this change DataView and TypedArray accesses themselves are mostly on par performance wise.
