8289534: Change 'uncomplicated' hotspot runtime options

[hseigel]

Please review this small fix to change range constrained JVM runtime options from 64 bits to 32 bits. This fix was tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and Mach5 tiers 3-5 on Linux x64.

Thanks, Harold

The changes seem fine, though the change to ObjectAlignmentInBytes is a bit disruptive. I don't really see a motivation for this though - the memory saving seems insignificant.
