".volatile - Defines the beginning of a block of instruction. The instructions in the section may not be changed. The block of instruction should end at a .nonvolatile pseudo-op and should not contain any Control Transfer Instructions (CTI) or labels."
".nonvolatile - Defines the end of a block of instruction. The instructions in the block may not be permuted."

All other methods in this file have these directives for long time so I copied it to be consistent.
This code will be backported only into JDK6 where we had these directives already.
