RFR: 8281455: Change JVM options with small ranges from 64 to 32 bits, for gc_globals.hpp [v2]

[Afshin Zafari]

> The `uintx/intx` options whose ranges are small enough are changed to `uint/int`, otherwise gcc complains 
> when `-Wconversion` is used in build.
> Their uses in printf formats are changed accordingly.
> 
> ### Tests
> Locally hotspot:tier1 tested on linux-x64
> mach5 tiers 1-4 on Linux and Windows 64bits platforms passed.
