Bunch of changes were necessary:

- attaching frame state to some JS nodes in a similar way to attaching
  context (this is quite ugly and we should take another look at this),
- new bailout point for the debugger statement,
- register allocation constraints for the frame states,
- generating translations and deopt entries, attaching them to
  safepoints,
- enabled one mjsunit test for debugger state that uses the generated
  frame state.

Refactor parser Checkpoints.

Why this is better:

1) Not needing an extra template parameter for Checkpoints ctors. This was
especially confusing since the template parameter was named Parser and Parser is
also used as a type name and is also a concrete type. This CL makes it clear
that ParserTraits::Checkpoint is consturcted with ParserBase<ParserTraits> -
that's the only sensemaking type for the ctor param anyway.

2) This CL makes ParserBase define a Checkpoint base class (which knows how
to create and restore a checkpoint with ParserBase) which
PreParserTraits::Checkpoint and ParserTraits::Checkpoint inherit, and not the
other way around.

This is a more intuitive way to implement the "base functionality + extending
it" concept than the previous solution. The previous solution was to allow
Traits to define a Checkpoint class and make ParserBase<Traits>::ParserCheckpoint
(which defines the base functionality) inherit from it.

3) This CL moves the Checkpoint class definitions out of the SomeTraits::Type
struct; SomeTraits::Type is supposed to be a collection of typedefs and not
contain anything else.

Checkpoints were introduced in r22925 ( https://codereview.chromium.org/443903003 ).

The bit counting functions provided by CompilerIntrinsics were undefined
for zero, which was easily overlooked and unsafe in general. Also their
implementation was kinda hacky and mostly untested. Fixed the
