Perf Improvements
shouldIntlComponentUpdate
Improved the perf of shouldIntlComponentUpdate util which now checks if context.intl is the same as nextContext.intl before doing a shallow compare of their filtered props.

Nested <IntlProvider>s
Creating Intl* formatter instances is expensive, so <IntlProvider> memoizes the Intl* constructors to reuse the formatter instances. These memoized formatters are now shared with nested <IntlProvider> instances.
This sharing should increase the rendering perf of component architectures which use nested <IntlProvider> instances.
