Track current task directly instead of computing from stack pointer
This is a precursor to supporting task-specific task sizes. I've
benchmarked this vs. the current stack pointer method; no measurable

BUG=chrome-os-partner:13814
TEST=boot EC; taskinfo; if it boots and doesn't print garbage, it worked
BRANCH=all
