This introduces a bailout point for class literals right after the
%DefineClass function has been called. Otherwise the FrameState after
class literal evaluation might contain the literal itself.

Lolcode candidate: Both Expression and FunctionLiteral define an accessor is_parenthesized(), which access different flags. FunctionLiteral derives from Expression.

Given
      FunctionLiteral* a; a->is_parenthesized()
const FunctionLiteral* b; b->is_parenthesized()

the first accesses FunctionLiteral::IsParenthesized, the second accesses Expression::IsParenthesizedField.

Since these are distinct uses, we could rename them based on their use:
- Expression::is_parenthesized -> is_single_parenthesized
  Count # of parenthesis, for parsing & error handling:
  no parenthesis -> single parenthesis -> multi parenthesis
- FunctionLiteral::eager_compile_hint()
  Hint from parser to compiler about whether the parser suggests this function for eager compilation.

Now all nodes that care about deoptimization always take frame state
inputs no matter whether deoptimization is enabled for a particular
function. In case that deoptimization is off, the AstGraphBuilder just
inserts the empty frame state. This greatly simplifies the logic in
various places and makes testing easier as well, and is probably the
first step towards enabling --turbo-deoptimization by default.

There seems to be no noticable performance impact on asm.js programs.

Also fix the graph replay in order to regenerate the scheduler unittests.
