> This patch streamlines and specializes various `String::indexOf` methods. > Mainly avoids the need for clamping and doing checks that are redundant in > almost all cases, moving the checks to the API boundary where they are > needed. > > This improves performance both at peak and during startup/warmup. Since > indexOf is heavily used in bootstrapping code it makes sense to slightly dial > back abstraction and delegation, which in this case also brought some benefit > to peak performance. > > Testing: tier1-3
