        Description

        The bot_updates parameter for the allocation methods is not necessary any more as the relevant G1AllocRegion instance for a particular allocation already has a _bot_updates member.

        Actually there are several asserts in the code that make sure that the bot_updates parameter passed down equals the _bot_updates member of G1AllocRegion.

        Some comments in the code indicates that passing the bot_updates parameter explicitly is an optimization that allows the compiler to compile out some branch. Look at whether this actually has any significant impact.
