Please review fix for 7196103: NPG: Unable to allocate bit map for parallel garbage collection for the requested heap size

[Vladimir Kozlov]

arguments.cpp:

   // 100,000 classes seems like a good size, so 100M assumes around 100 bytes

100Mb/100000 = 1Kb, not 100 bytes :)

Otherwise looks good.

Thanks,
Vladimir
