------- Additional Comments from Cosmin Truta <ctruta at gmail.com>
I initially made DFG::isARMWithIntegerDiv() in order to use it as it's the case
with DFG::isX86(), i.e. when it's not protected by #if CPU(...); but then I
noticed I had used it inside in ARM-specific code also, interchangeably (and
inconsistently) with MacroAssembler::supportsIntegerDiv(). I am now modifying
the previous patch: I use MacroAssembler::supportsIntegerDiv() consistently
inside ARM-specific code, and DFG::isARMWithIntegerDiv() only in the rare cases
outside.

I also simplified isIntegerDivSupported().
