expectations.
We are currently using a rather old version of the ES5 conformance
tests and there has been a range of bug fixes in the test set. This
change brings us up to date.
In addition, our current test expectations discards the all chapters
but chapter 15. I have enabled the other chapters, cleaned up the
tests that we no longer fail on, and filed bugs for tests that we fail on.
It seems some of the bugs on the es5 conformance bug-tracker has been
fixed but not marked fixed. I will file bugs for the newly discovered
test bugs.

Similar or duplicate checks are scattered around the code before doing the dictionary load.
Also the entire branch in GenerateCallNormal that handles global/builtin receiver is
guaranteed to bail out from GenerateDictionaryLoad, so there is no point in generating it at all.
The purpose of the patch is:
- making C++ code more compact and transparent,
- not generating dead code.
There is a tiny performance gain. The patch is ia32 only for now.
