Implement many KeyedStoreStubs using Crankshaft

- Addition of a compiled hydrogen stub for KeyedStores.
- Inlining of "grow" stubs into OPTIMIZED_FUNCTIONs
- Addition of new "ignore OOB" ic stub that silently swallows out-of-bounds stores to external typed arrays.
- Addition of new "copy-on-write" ic stub that inlines allocation and copying operations for cow array
- New stub are generated with Crankshaft, so they are automatically inlined into OPTIMIZED_FUNCTIONs
