vegorov@google.com 339c914f2c Ensure that compile time types for comparisons are recomputed once comparison are specialized. 
Turn CompileType into a value object instead of zone object. Provide a transparent zone allocated wrapper for CompileType. This simplifies code paths that recompute and update type and reduces number of allocated zone objects.

Split ComputeInitialType into ComputeInitialType and ComputeType.

ComputeType returns values type as a value object. ComputeInitialType returns a pointer and by default it delegates to ComputeType.

This split reflects differences between instructions: majority of them have their own type, but some can return the type of an input which should not be unwrapped and rewrapped again because this will destroy the connection between types.

vegorov@google.com bb0c073ff9 Strengthen type assertions post-dominated by checks during type propagation. 
If a type assertion for a value is post-dominated by a class or smi check over the same value then raise the check over the assertion.

This allows to eliminate type assertions in the cases like:

AssertAssignable(x, int)
CheckSmi(x)

Currently post-domination is computed within a single block because post-dominators are not available.
