[10] RFR(S): 8179026: Remove explicit code cache options processing

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8179026
http://cr.openjdk.java.net/~thartmann/8179026/webrev.00/

I've removed the explicit processing of -XX:CodeCacheExpansionSize, -XX:NonNMethodCodeHeapSize, -XX:ProfiledCodeHeapSize
and -XX:NonProfiledCodeHeapSize because generic option processing already supports memory values. I've also added a
lower bound of vm_page_size() to all of them except the non-profiled and the profiled size because these can be 0. The
actual checking is done in codeCache.cpp.

All tests pass.

Thanks,
Tobias
