f395ccd6db X87: [turbofan] Implement throwing exceptions into TurboFan code. 
port 1382879f29 (r27016).

oringinal commit message:

    [turbofan] Implement throwing exceptions into TurboFan code.

    This extends the stack unwinding logic to respect optimized frames
    and perform a lookup in the handler table to find handlers. It also
    contains fixes to the API call stubs to allow a stack walk while
    promoting scheduled exceptions.

adb8867337 [turbofan] Add explicit set for nodes with weakened types. 
To ensure termination, we need to be sure that once we start weakening
a node, we keep weakening that node in subsequent re-typings. Until now,
we were guessing that we previously weakened from the type. This
change introduces a set of nodes that have already be weakened, so
that we have a reliable way to detect previous weakening.

3c3ce1bca8 Parser: Fix crash on stack overflow when lazy-parsing arrow functions 
The problem manifests itself when parsing manages to return something
meaningful in the presence of a stack overflow. This happens because
calling ParserBase::Next() will still return one valid token on stack
overflow, before starting to return invalid tokens.

Take the following input as example:

        a.map(v => v + 1);
              | |
       already   next token
        parsed   (which will be an invalid token
  (identifier)   because of a stack overflow)

The "v" may have been already parsed into a VariableProxy, then if a
stack overflow occurs, next token will be an invalid token (instead
of Token::ARROW), but the parser will return the VariableProxy.

This always happens when lazy-parsing arrow functions, so the position
in the input stream where the the arrow function code ends is known.
This fix adds a check that ensures that parsing ended at the end
position of the arrow function.

b7dc9c580a [turbofan] Remember types for deoptimization during simplified lowering. 
With this change, we remember the types of frame state inputs (in a new
operator, called TypedStateValues). Instead of inferring the value types
when building translations, we used the recorded types.

The original approach was not reliable because the passes after
simplified lowering can change node types, and this in turn confuses
the translation builder.
