JDK-8324181 - enhance compressed streams
Description
The nmethod "scopes" data section contains a significant portion (10% - 20%) of the size of nmethod. The data is compressed using the Pack200 algorithm. Using the fact that half of the data in the partition contains zeros, the partition size of these regions can be reduced by another 30%.
