Bhuwan Khattar c16574a0b4 Don't special case performanceNow
Summary: The previous version of `performanceNow` used to reassign to a `require(...)` alias, which our inline requires transform guarded against. Before the update to React 0.14, we were pulling `performanceNow` from a hardcoded `react-tools` version (b4e74e38e4/src/shared/vendor/performance/performanceNow.js), so we couldn't just fix the file and had to special case it. Now that we've updated to React 0.14, `performanceNow` is pulled from fbjs and no longer needs to be special cased.
