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.

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.

  mov(ip, Operand(target, rmode), LeaveCC, cond);

Changed a JS call in the compare stub to a tail call to avoid GC
problems where the pushed return address is not updated on GC.

* 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.

Added newly added instructions to test-disasem-ia32.cc and implemented the missi
ng ones in the disasembler.

Added some asserts to 8-bit instructions which only work with eax, ebx, ecx and
edx (al, bl, cl and dl).

Removed the loope instruction.

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.

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.
