f853b08ad0 Fixed constant folding in HMod. 
We have to check for overflow before attempting to do a modulo operation,
otherwise Crankshaft itself segfaults on some platforms, e.g. ia32. Added tests
even for division, where the problem doesn't show up, just to be sure...

This will be relevant after Persistent is changed to Dispose itself when

3f09e0a3d8 Remove separate maps for function instances 
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals.  For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().

However, since 2009 or so, both maps have been the same!  Both have had
writable, non-enumerable prototypes.  Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.

This patch removes the separate maps for function instances in sloppy
and strict mode.

911c14556d Cleaned up Crankshaft pipeline a bit. 
Two tiny changes:

  * Some phases were missing an HPhase, which was added, so we can now see all
    phases in the visualizer output.

  * Consistently test commandline flags directly in the pipeline, making it
    clearer which parts are optional and which are not.
