Recognize special comparisons via pattern matching on the hydrogen graph.
...
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.

Refactor how embedded pointers are visited.
...
This refactoring (almost) gets rid of the requirement to get the target
object address for an object pointer embedded in code objects. This is
not possible on MIPS as pointers are encoded using two instructions. All
usages of RelocInfo::target_object_address() are (almost) obsoleted by
this change. The serializer still uses it, so MIPS will not yet work
with snapshots turned on.
