Changed the code_range_size's type from int to size_t as Sven suggested.

Some try bots are not happy with this CL, see above...

Changed the assertion to ASSERT(!kRequiresCodeRange || requested <=
kMaximalCodeRangeSize);

I am glad I could access trybots now, thanks Michael!

An alternative is to run those test under V8_TARGET_ARCH_X64 ||
V8_TARGET_ARCH_ARM64 so that the code range feature is tested for the ports
requiring it.

LGTM (and the bots ;-), I'll land it for you.
