[Interpreter]: Use vector store for array literal computed stores.

[Interpreter]: Use vector store for array literal computed stores.

Replaces the use of KeyedStoreICGeneric with a vector based KeyedStoreIC for
array literal computed stores now that there is a feedback vector slot for
these expressions. Removes KeyedStoreICGeneric bytecode since this is no
longer necessary.

Michael: This CL replaces the generic keyed store on array literals with the
vector store now that there is a feedback slot available. PTAL, thanks!

lgtm, very nice!

TBRing Michi for minor change in compiler/bytecode-graph-builder.cc to remove
the Generic KeyedStoreIC bytecode.
