64c96ad9c0 There is a trick for speed up array shift operation. 
This trick is confusing a bit the heap snapshoting code.
Such a shiffted array will be interpreted as a new array in the second snapshot.

b0bb4f078a Fix assertion failure due to too many deoptimization ids. 
The failing mozilla test was caused by more deoptimizations
introduced by --always-opt and r11087.

We abort code generation in release mode, so we should do
the same in debug mode.

e081a3bfba Insert explicit deoptimization for named loads that have "uninitialized" type feedback. 
We already do this for binary-ops, unary-ops and comparisons. Typefeedback for named loads can now also
be in "uninitialized" state which means that the corresponding load IC was never executed.

79a98de9f7 Fix declarations escaping global strict eval. 
According to ES5 10.4.2(3), eval calls of strict code always require
their own lexical and variable environment. For now we just add a new
scope when we parse the strict mode directive. The clean solution would
be to always have this sope present (even for global eval calls) and
adapt variable binding to cope with that.

c644c4e811 Ensure that generated code for object literals will call Runtime_DefineOrRedefineAccessorProperty only once per accessor property. 
To do this, we collect all accessor properties in a first pass and emit code for
defining those properties afterwards in a second pass.

As a finger exercise, the table used for collecting accessors has a (subset of
an) STL-like iterator interface, including STL-like names and operators.
Although C++ is quite verbose here (as usual, but partly this is caused by our
current slightly clumsy classes/templates), things work out quite nicely and it
cleans up some confusion, e.g. a table entry is not an iterator etc.
Everything compiles into very efficient code, e.g. the loop condition 'it !=
accessor_table.end()' compiles into a single 'testl' instruction on ia32.
+1 for using standard APIs!

35786621f2 Change --hydrogen-filter to allow specifying a negative filter for optimized functions. 
When prepending a '-' to the function name, the function will not be optimized.

--hydrogen-filter=foo works as before.

--hydrogen-filter=-foo means don't optimize foo.
