ede65c19a1 Remove a pair of problematic uses of the Reference utility class from 
the code generators.

These uses broke the rules of the class because it was safe to do so,
but there was no real reason to do it that way.

39b9f57f19 Cleanup the handling of control flow in the toplevel code generator. 
Do abstract the setting and restoring of 'argument' state into a
function that takes arguments.

Do not set the argument state in the code generator unless it
represents arguments to a recursive call to Visit.

fdba189730 Fix a problem with const initialization in the top-level code generator. 
When initializing the special local variable containing the reference to the enclosing 
function in named functions we now (correctly) emit an INIT_CONST instead of INIT_VAR,
and we correctly bail out in the top-level code generator.

Also part of this change is adding missing statement position information 
for some statements in the top-level code generator.

612d9b82f0 Add some interfaces to the GC that allow us to reserve space. This is needed 
for partial snapshots.  After reserving space we can be sure that allocations
will happen linearly (no GCs and no free-list allocation).  This change also
contains the start of the partial snapshot support, which, however is not yet
completed or tested.

f0b8c2d97a 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.

903301248e Improve keyed loads on strings by using a new stub. 
Instead of going through a runtime function for keyed loads
on strings we invoke a separate specialized stub that
assumes string as receiver type and the key to be a number.

The stub calls a JS builtin function to return the corresponding one-character string.

3d36c712aa Use generated code to create sub strings. 
Added a stub to allocate and fill a string object with a substring from another string.

Use the rep movs instruction to copy the string data as it turned out to be the fastest way.

While preparing this I experimented with some SSE2 instructions, so the instructions movdqa and movdqu are still in the IA-32 assembler even though they are not used.
