Reimplement dynamic frame alignment for frames that are compiled via OSR or have more than 2 double spill slots.

The first spill slot is now reserved on all optimized frames to distinguish frames that were aligned.

Reland r11425 "Re-enable optimization for hot functions that have optimization disabled due to many deopts."

Fix performance regressions introduced in r11425 by
- counting number of function deoptimizations instead of function optimizations,
- packing several counters into one field of shared function info.

This is a first step towards separating all transitions from the property descriptions. If we link the property descriptions from the transition object, this will in allow the descriptor array (property descriptions) to become immutable.

- Extend HValue interface to allow splitting observed input representation (comming from type feedback) from required input representation (dictated by instruction itself). Currently all instructions except for bitwise binary operations have this representations match. For bitwise binary operations hydrogen builder unconditionaly forces Integer32 representation for those operations that have Double type feedback. Thus causing representation inference to incorrectly count such uses as Integer32 instead of Double. This change also prepares for more fine grained type feedback for inputs of binary operations.

- For phies that are not convertable to Integer32 discard direct and indirect use count of Integer32 type to avoid propagation of these uses to connected phies.

This compiles against a given closure instead of the shared function
info, which is a prerequisite for enabling lazy compilation of inner
functions within a closure with non-trivial context.

The serialized node structure currently holds an index
of its first containment edge in the edges array.
The index can be quite big (up to 7 digits for large snapshots).
The patch changes the serialization format to pass
node containment edge count instead. For most nodes the count
is just a single digit number.
This reduces serialized snapshot size and therefore its transfer time.
