BUG=chrome-os-partner:46063
BRANCH=None
TEST=Enable CONFIG_REPLACE_LOADER_WITH_BSS_SLOW on GLaDOS.  Build,
flash, and verify that AP and EC boot.  Perform typing test with no jank
or other oddities.
TEST='sysjump rw' and repeat the typing test.
TEST=Hold down arrow down and issue 'reboot' command.
TEST=make -j buildall tests
