Some cleanup of the toplevel code generator:
...
* Rename the operation of filling a context with a value. Formerly it
was 'Move', now it's 'Apply' so as to avoid confusion with various
other Moves (eg, in the toplevel codegen, in the macro assemblers).
* Use the abstraction Drop rather than math on the stack pointer.
* Add a predicate on AST expression nodes to abstract a repeated test
whether we should us a regular (named) IC or a keyed IC.

Remove the last context dependent reference from the Script object
...
For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object.
The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

Top-level compiler: Re-allow non-lazily compiled function literals.

This change re-allows non-lazy compiled function literals for top-level compilation.
There was a problem on ARM exposed through this change which was fixed as part of r3289
in fast-codegen-arm.cc (Threading and Threading2 tests failed)
It occurred before r3289 when we allocate a local context at the beginning of a function. The
code for the stack check was split up in an unintended way (load of stack check limit into r2,
and use of r2 in the actual stack check code).
