9095abb776 Introduce 'top-of-stack caching' to the toplevel code generator by 
allowing the value of the rightmost subexpressions to be evaluated
into an accumulator register (eg, eax, rax, or r0) rather than onto
the stack.

a5ac66628d Small optimization of ARM compare stub. Reverse all references to 
left and right sides of the comparison to reflect reality.  Don't
check explicitly for NaNs when using VFP3 since the compare
operation can signal this case with the v flag.  Use cmp instead
of tst in the fast compilers since tst leaves the v flag unchanged
and thus can only work by accident on non-equality comparisons.

562f90d375 Ensure correct boxing of values when calling functions on them 
When a function is called with a value type as the receiver this is now boxed as an object.

This is a low-impact solution where the receiver is only boxed when required. For IC calls to the V8 builtins values are not boxed and as most of the functions on String.prototype, Number.prototype and Boolean.prototype are sitting there most IC calls on values will not need any boxing of the receiver.

For calls which are not IC calls but calls through the CallFunctionStub a flag is used to determine whether the receiver might be a value and only when that is the case will the receiver be boxed.

No changtes to Function.call and Function.apply - they already boxed values. According to the ES5 spec the receiver should not be boxed for these functions, but current browsers have not adopted that change yet.

bd06358b93 Optimized calling of C++ builtins (and HandleApiCall 
in particular).

  * Called function is passed on the stack instead of
    using a static variable.

  * Builtins that don't need the called function don't
    get it.

  * Made is_construct statically known to HandleApiCall
    by setting custom construct stub for API functions.

* Refactor VisitProperty to use the platform-specific methods for emitting the IC calls.

* Correct the recorded source positions for assignments and property loads.
* Fix bug on x64 where source positions were not recorded before a calling a call-IC.
* Correct some inconsistencies between IA-32 and X64 top-level code generator.

We now pass all regression tests with 
--always-fast-compiler.

acf74b04a7 Fix a problem when compiling built-ins with the top-level compiler. 
Replace runtime call to NumberAdd with call to binary op stub.

Until now the top-level compiler always called a runtime function
for count operations. 

In some places we expected in the JS builtins smis as arguments.
If we perform a count operation before all smis would get converted into
heap numbers by the runtime number add function and result in a runtime 
assert.

Also: Add missing debugger information in the top-level compiler for 
do-while loops.

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

61a1c089e4 Change the ARM fixup code to handle the use of the following 
instruction sequence for jumps:

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