Remove SminessPropagator and FlowGraphTypePropagator and all associated infrastructure and fields.
Replace multiple fields (result_cid_, propagated_cid_, propagated_type_, reaching_cid_) with a single field of type CompileType which represents an element of type analysis lattice and incorporates information about: value's nullability, concrete class id and abstract super type. This ensures that propagated cid and type are always in sync and complement each other
Implement a new FlowGraphPropagator that propagates types over the CompileType-lattice.

Introduce InvokeMathCFunction that can be used to directly invoke mathematical
function provided by runtime.
Use it to unconditionally inline _Double.pow.
Use it to inline floor, ceil, round, truncate, round when SSE4.1 is not
available.
Perform representation selection phase after constant propagation to minimize
boxing.
Add support for enter instruction in the x64 disassembler.
Add test for optimized pow and fix compilation on windows.
