RFR: 8321512: runtime/CommandLine/OptionsValidation/TestOptionsWithRanges.java fails on 32-bit platforms

[Thomas Schatzl]

Hi all,

  please review this fix for a failing test on 32 bit platforms. In particular, for the `G1CardSetArray` card set container the existing code tries to optimize memory usage by changing the number of entries (`G1RemSetArrayOfCardsEntries`, each entry taking 2 bytes) so that the resulting memory usage is 8 bytes aligned (because the allocator used aligns to 8 bytes anyway, so why not use that space).

On 32 bit platforms, the calculation results in an invalid size (> 2^16).

The suggested fix removes this automatic container size optimization: it is only used for the rare case when the knowledgeable user modifies the defaults; in that case I propose to have the user worry about optimal usage of the memory too, and simplify the code.

Testing: failing test passes

Thanks,
  Thomas
