STOP: optimize size of stop images
1) optimize scom with no rc and directly inline asm(saved for 2K :D)
2) initialize all variables(doesnt really save size, just good guideline)
3) loop both cores when block is big and redundant(saved only 50B -_-)
(50b for 3 blocks, each block saves 17b, or 4 instructions)
4) improvement on history update(saved 500B more :))
5) functionalize the exit catchup routine which is identical twice
(this back fired and cost us 100B :()
6) functionalize the eval eimr override macro which is identical twice
(saved 130B :|)
7) finally the saving is about 2728B on CME
8) apply history update tech to sgpe, found bug in the tech, fixed
(but our saving is back to ~2500B)
9) clean up sgpe redundent ex branching code
(same as cme saved only about ~60B)
10) rebase
