Added a version of the v8::HandleScope constructor with an Isolate and use that consistently.
...
I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

Cleaned up CpuFeature scope handling.
...
First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.
Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

Made Isolate a mandatory parameter for everything Handle-related.
...
Unified parameter order of CreateHandle with the rest of v8 on the way. A few
Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.

ARM: Change signature for vmov.32 function in the assembler
...
The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.
The situation is dangerous because C++ will happily implicitly convert between
int and double.
This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

Fixed a bug in the chaining of fixup position
...
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.
Unified the code for Assembler::next on ARM and MIPS while we were there.
Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}
