This reverts commit 812eb264.

Reason for revert: clusterfuzz crashes

Original change's description:
> [compiler] Cache StateValue processing in InstructionSelector.
>
> Processing StateValues into operands is one of the most costly
> parts of instruction selection. As it happens, StateValues are
> shared by many nodes, and so we are unecessarily reprocessing
> the same StateValues multiple times. This CL introduces caching
> for the processed StateValues enabling very fast emitting of
> operands for subsiquent instructions with the same StateValue.
> The hitrate for the cache is higher than 90% on most optimizations.
