Previously the preparser always accepted natives syntax and let the
real parser throw the syntax error. In ES5, it should be an early error,
so the preparser must catch the error.
The perparser library does not expose parsing for natives syntax, it's
only used internally.

1. Record AST id for CallFunctionStub.

2. Correctly extract cached target from CallFunctionStub inline cache.

3. Fix a bug when inling call as a function in effect or value context:
   Handle abnormal exits correcty.

4. Fix a bug when inlining call as a function in test context: drop function
   correctly from true and false block.

5. Avoid inlining mutually recursive functions by checking the stack of function
   states before inlining. This was not a bug, but is just a more general
   check to avoid recursive inlining.

Currently, preparser-process crashes when given flags with arguments (e.g. --gc_interval 10). It can be fixed by ignoring everything in the command line except the "throws" command and its immediate arguments. This assumes that no flags appear between "throws" and its arguments.

Previously, comparisons against null/undefined and comparisons of the result of
typeof against a constant string were done syntactically. Now we do this via
pattern matching on the hydrogen graph, which opens up more opportunities for
better code generation, e.g. the following comparisons are now recognized to be
special:

   var bar = typeof foo;
   var baz = "undefined";
   if (bar == baz) ...

   var blah = undefined;
   if (hurz == blah) ...

If we did this handling of special cases even later at lithium generation time,
even more cases could be recognized, but this would involve bigger changes and
this CL handles most common cases.
