RFR (XS): 8015635: Crash when specifying very large code cache size

[Vladimir Kozlov]

We don't place 'else' on separate line and remove comment inside 'if' body and change it to:

} else if (ReservedCodeCacheSize > 2*G) { {
   // Code cache size larger than MAXINT is not supported.

Thanks,
Vladimir
