Fixed undefined behavior in RNG.

We're basically trading undefined behavior for implementation defined
behavior, which should be OK for UBSan. :-) The generated code should
be identical, at least I checked that for GCC 4.6.3 on x64.

X87: Fixed flooring division by a power of 2, once again...

port r21769

original message:
    Avoid right shifts by zero bits: On ARM it actually means shifting by
    32 bits (correctness issue) and on other platforms they are useless
    (performance issue). This is fix for the fix in r20544.

Remove one more arch-specific target name.

One more target had the architecture added to its name since r14209
originally landed and was missed when that change was reverted. Remove
the architecture from v8_libbase as well.

Optimize Function.prototype.call

- May inline the function, or call it directly, instead of going through call
- Supports arguments object escaping when it escapes to builtins (preparation for slice.call(arguments, ...) optimization)
- Both .call and .apply now support inlining when calling builtins indirectly
