140ae348d2 Recognize special comparisons via pattern matching on the hydrogen graph, 2nd attempt. 
This time, we initially leave the HTypeof instruction in the Hydrogen graph,
even for the special cases. We later try to remove this instruction (and any
HConstant) in the canonicalization pass, if possible. Always removing the
HTypeof during the initial graph construction is wrong if e.g. it is used in an
HSimulate.

The removals can be generalized a bit, but this will happen in a separate CL.

2bbf3bbee7 Make native syntax an early error in the preparser. 
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.

de7b222e36 Support for precise stepping in functions compiled before debugging was started (step 2) 
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

3fabe323f2 Add kHeaderSize constant to SeqString. 
This prevents potential misuse of SeqString::kHeaderSize as in the
case of live byte counting in incremental marking stub. All stubs
picked up the undefined size constant SeqString::kHeaderSize, thus
the computed size of all strings was off by two pointers slots.

610281f4ee Fix calculation of live-bytes in pages. 
The "live bytes" count is *really* a "marked black" count - i.e., the count of bytes *known* to be live.

Fix aggravating bug on X64 where assembler code used a value that was off
by a factor of 2^31.

Ensure that sweeping clears live-bytes. Added other missing increments.

Added print statements to trace live-byte modifications, under a flag.

Still a few cases of undercounting left.

(New issue to merge from GC branch to bleeding_edge)

76c869434d Fix a bug with uninitialized const variables in the optimizing compiler. 
We have to check for uninitialized uses before phi-elimination. Otherwise we
may miss such a use and result in using the hole value instead. This
causes a NULL-dereference or assertion failure.
