That makes it easier to maintain the code---one should care less
about releasing the memory as smart pointers would take care of
this.

Switch to ScopedVector instead Vector for the same semantics in
src/builtins.cc

The calling convention for keyed load IC is changed to have the key passed both in a register (r0) and on the stack.

Next steps will be first to remove the key from the stack and then pass the receiver in a register (r1).

This runtime function should operate on elements and thus 'receiver'
must be JSObject and indices should be numbers.

This is mainly a port of r3899. It also adds handling of initilization blocks in ARM which had no special handling before.

The "calling conventions" used for

  EmitNamedLoad
  EmitNamedStore
  EmitKeyedLoad
  EmitKeyedStore

are somewhat mixed, but will become more aligned as the use of register allication and passing of argument in registers to IC's is extended.

Added a simple new space check on the elements fixed array which can allow
updating with other values than smis without updating the remembered set.

Also combined the positive smi and range check so that a separate smi check can be avoided when the key is known to be a smi.

This is a port of r4543.
