c80cba3bcc Add the for statement back into the set of things the 
non-optimizing compiler can cope with.  By default it bails out
to the old compiler on encountering a for loop (for performance)
but with this change the --always-fast-compiler flag will enable
functions with for loops to be compiled in the non-optimizing
compiler.  Also enables the non-optimizing compiler on functions
that can be lazily compiled (again only with the flag).

c757fa4604 Refactor GenericBinaryOperation and its helper functions to always return a Result. 
This is a preparation step for including number type information
in the virtual frame. We need a common place where we can update
the number type information of the result of a binary operation
since we should not modify the state of the virtual frame elements
directly.

3e8539d873 First step of refactoring expression contexts in the toplevel code 
generator.

Contexts are no longer stored in the AST but in the code generator's
state.  This means that the running the code generator selector is not
required to use the toplevel code generator (for instance, if we
already know that we can and should use it).

5aeb48f366 Added ES5 conform tests for getOwnPropertyNames. 
Most of the test cases fail as the different objects according to the tests 
can not have additional properties attached to them. I will file a bug report
on the es5 conform site as they should allow this. Some of the test fails
because we still miss some of the es5 features used.

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot. 
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

a5ac66628d Small optimization of ARM compare stub. Reverse all references to 
left and right sides of the comparison to reflect reality.  Don't
check explicitly for NaNs when using VFP3 since the compare
operation can signal this case with the v flag.  Use cmp instead
of tst in the fast compilers since tst leaves the v flag unchanged
and thus can only work by accident on non-equality comparisons.
