8d51195778 Fixed issue 619 allowing Object.create to be called with a function. 
This change allows Object.create to take a function as input in the
proto argument. The spec says that Type(O) for the proto argument
should be true but our IS_OBJECT does not check for this. I will make a
IS_SPEC_OBJECT in macros.py and refactor v8natives in another CL.

fb3e01a306 Correct issue 696 with Date.parse returning a value when called on a non date string. 
The error was introduced in revision 4557 where support was added for
ES5 date time format strings. Because there was no check for a valid
year a random string starting with a non-digit character would be
parsed.

This change disallows ES5 formatted dates where there is no date
fraction (i.e., with only a timestamp). Since none of the other
browsers support Date.parse on only timestamps I have disabled this
totally instead of just correcting the parser.

856135af42 Implement fast calls of functions in the presence of eval (if the eval 
calls do not introduce new bindings).

The infrastructure is already in place for fast loads from context
slots in the presence of eval.  This change simply uses that
infrastructure for calls as well as loads.

89a7341d3f Pass key and receiver in registers for keyed load IC on ARM 
The calling convention for keyed load IC's on ARM now passes the key and receiver in registers r0 and r1.

The code path in the ARM full compiler for handling keyed property load now has the same structure as for ia32 where the keyed load IC is also called with key end receiver in registers.

This change have been tested with an exhaustive combinations of the flags

  --special-command="@ --nofull-compiler"
  --special-command="@ --always-full-compiler"
  --special-command="@ --noenable-vfp3"

to the test runner.

528ab2bc7d Refactor assignment in the ARM code generator 
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.
