The point at which we reloaded the loader was too early. When items are placed into .bss.slow via CONFIG_REPLACE_LOADER_WITH_BSS_SLOW, other tasks could still access their variables that may have been in that region after we had replaced those contents with the loader. This commit moves the reloading of the loader to as late as possible once all tasks have done their HOOK_SYSJUMP work. Also, fixed a bug with the .bss.slow section. If a board is not using the config option but items are placed in that section, that part of RAM would not be cleared out. BUG=chrome-os-partner:46056 BRANCH=None TEST=Enable config option on GLaDOS and add a few variables to the .bss.slow section. 'sysjump' between RO and RW and verify that no data bus error is encountered.
