Moved check that ReservedCodeCacheSize >= InitialCodeCacheSize to Arguments::check_vm_args_consistency(). As a result, the ordering in which the two parameters are given to the VM is not relevant. Added a regression test.

The VM exits when the condition in the subject line applies. The fix sets InitialTenuringThreshold to MaxTenuringThreshold if it is larger than MaxTenuringThreshold and InitialTenuringThreshold has not been set (is default).

Refactor G1's hot card cache and card counts table into their own files. Simplify the card counts table, including removing the encoding of the card index in each entry. The card counts table now has a 1:1 correspondence with the cards spanned by heap. Space for the card counts table is reserved from virtual memory (rather than C heap) during JVM startup and is committed/expanded when the heap is expanded. Changes were also reviewed-by Vitaly Davidovich.

Make processing of minimum, initial and maximum heap size more intiutive by removing previous limitations on allowed values, and make error reporting consistent. Further, fix errors in ergonomic heap sizing.

Supply a new flag -XX:+AssumeMP to workaround the problem. With the flag is turned on, assume VM run on MP platform so is_MP() will return true that sync calls will not skip away.

Ergonomics now also takes available virtual memory into account when deciding for a heap size. The helper method to determine the maximum allocatable memory block now uses the appropriate OS specific calls to retrieve available virtual memory for the java process. In 32 bit environments this method now also searches for the maximum actually reservable amount of memory. Merge previously separate implementations for Linux/BSD/Solaris into a single method.
